PEARL BLADES Car Parts
Pearl Blades on this page contains three products with two unrelated functions. RBA727 is a rear wiper arm-and-blade assembly described for a Corsa application. The other products are 11 x 16mm mini blade fuses with breakout wires in 10A and 15A ratings. Their catalogue descriptions name Wot-Nots, a Pearl Automotive retail brand, so the collection should not imply that the wiper and fuses form one technical blade system.
For RBA727, confirm the vehicle registration or VIN, model generation, body style, build date, rear-screen arrangement and full Pearl application reference. The word Corsa alone is too broad. Compare arm length, blade length, spindle spline, retaining nut, park angle, washer-jet path and clearance from the glass edge or spoiler. A rear wiper must park without striking trim and sweep the intended area with even pressure. The current AutoMotoPart selection contains 3 Pearl Blades items, led by 3 maintenance entries. These Pearl Blades figures describe the range on this page rather than every product the brand may make elsewhere.
For a breakout fuse, recover the circuit diagram and identify why access to the fused side is needed. Confirm standard mini blade—not low-profile mini or Micro2—plus the original fuse rating, vehicle-system voltage, wire gauge, insulation, connector and proposed measuring or auxiliary load. The 10A and 15A values are not choices for increasing capacity. A fuse protects the supported conductor and circuit; replacing 10A with 15A can allow damaging current before it opens.
Isolate power by the vehicle procedure before wiper or fuse-box work. Keep the wiper arm controlled because its spring can snap the blade or bare hook against glass. Use the correct puller where the taper is seized, torque the nut to vehicle data and test with a wet screen. At the fuse box, do not probe restraint, braking, steering, high-voltage or other safety-critical circuits without the approved diagnostic method. Route the breakout wire clear of covers, terminals and heat; add any new circuit through a designed fused interface rather than treating the lead as an unlimited feed. The long guide below keeps exact fitment, circuit protection and post-work checks neutral.

Pearl Blades: understand the range before choosing
This Pearl Blades page is a mixed maintenance selection rather than one blade family. It contains Pearl Automotive rear wiper arm-and-blade reference RBA727 for an exact Corsa application, plus two mini blade fuses with breakout wires rated 10A and 15A whose current descriptions identify the Wot-Nots retail range. Wiper fitment and circuit protection must remain separate.
AutoMotoPart currently lists 3 Pearl Blades items. The largest Pearl Blades groups are 3 maintenance entries. Pearl Blades totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Pearl Blades listing, its current technical information and the item in front of you must agree.
What the Pearl Blades page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Maintenance | 3 | Select RBA727 by exact vehicle and rear-wiper geometry; select each breakout fuse by fuse format, original rating, circuit design, wire capacity and intended diagnostic or auxiliary method. |
One of three items is a wiper arm-and-blade assembly, while two are electrical fuse products. The fuse pair shares mini-blade geometry and breakout-wire format but differs at 10A versus 15A. Product identity, rating and purpose must stay attached to each item; neither fuse is related to the physical wiper blade merely because both use the word blade.
Build a reliable shortlist
Begin with two separate records. For the wiper, record vehicle and removed-part dimensions. For a fuse, record fuse-box position, circuit name, original rating, fuse style, supply side, protected side and current demand. Never use the wiper listing to infer fuse fit or a fuse colour to identify an unknown circuit.
| Check | Why it matters | Useful evidence |
|---|---|---|
| RBA727 application | Corsa generations and body styles can use different rear systems | VIN, current Pearl guide and removed arm geometry |
| Wiper mounting | Spline, nut, arm offset, blade length and park position must align | Spindle condition, dry trial position and wet-screen test |
| Fuse format | Mini, low-profile mini and Micro2 are distinct | 11 x 16mm product, socket and original fuse |
| Fuse rating | 10A and 15A protect different supported circuit capacities | Vehicle diagram and original specified amperage |
| Breakout wire | Lead gauge and connection method limit safe auxiliary use | Exact product data, new-load current and separate protection |
| Circuit consequence | Some fuse positions control safety, security or network functions | Manufacturer diagnostic procedure and competent technician |
A breakout lead is not automatically an add-a-circuit adaptor. Establish whether it is intended for measurement, switched signal access or another documented use, and determine how the original circuit remains correctly fused. Do not splice a new load until the design and protection at both ends are known.
RBA727 rear wiper arm and blade
The current title names Corsa but does not specify generation or body. Use Pearl's application guide and the vehicle identifiers to confirm RBA727. Compare the existing cap, nut, spline depth, arm bend, blade attachment, overall reach and park side. Inspect the spindle for corrosion and free movement before blaming the arm for slow or incomplete wiping.
Protect the rear glass with a thick clean pad and lift the spring-loaded arm carefully. Mark the original park angle before removing the nut. If the arm is corroded to its taper, use the supported puller rather than levering on glass or the motor shaft. Clean only as the repair method allows, position on the correct spline and torque without overtightening the spindle or crushing plastic trim.
Wiper blade contact and wet testing
Inspect the rear glass for chips, deep scratches and contamination. Check the washer outlet and hose before running a new rubber edge over a dry dirty screen. The blade should sit evenly without the arm twisting it, and its ends must clear trim, badges, high-level lamps and spoiler features through the full sweep.
Test first with the screen thoroughly wetted and the tailgate closed. Confirm direction, sweep, park, washer aim, noise and motor stop. A missed arc can come from worn spindle linkage, incorrect arm indexing, weak spring or wrong blade geometry. Do not increase arm pressure by bending it; diagnose the application and mechanism instead.
10A and 15A mini blade formats
The two fuse products are described at 11 x 16mm, the typical mini-blade envelope, with breakout wires. Confirm the delivered blade width and height against the vehicle socket because low-profile mini and Micro2 formats can look similar. Use only the rating specified for the original circuit: red 10A and blue 15A colour conventions are useful cross-checks, not a substitute for the printed value and diagram.
A higher fuse does not cure nuisance opening. Repeated failure indicates an overload, short, damaged component or wrong diagnosis that must be found. Inspect terminals for heat, looseness and corrosion and avoid gripping a fuse with metal tools while live. Replace a fuse only after the fault and supported rating are established; never bridge the blades with wire or foil.
Using a breakout wire responsibly
A breakout wire may provide a convenient connection, but its exact topology must be understood. Identify which blade connects to supply and which to the protected circuit, how the fuse element remains in series and the maximum current the lead and termination support. Check whether the product is intended for a test instrument, trigger signal or auxiliary feed before crimping anything.
For a new accessory, calculate operating and inrush current, confirm the chosen source can supply it and protect the new wire close to the source by an approved method. Use the correct crimp terminal and tool, insulate the joint and provide strain relief. Do not trap the wire beneath the fuse-box lid or route it over sharp brackets, pedals, airbags, steering joints or hot HVAC and engine parts.
Electrical verification and fault boundaries
Reconnect the battery and initialise vehicle functions only by the manufacturer procedure. Check the original fused circuit before the new connection, then measure voltage drop and current with appropriately rated instruments. A lead that becomes warm, a discoloured socket, unstable module behaviour or repeated fuse operation requires immediate isolation and redesign or repair.
Some vehicles monitor fuse states, switch loads electronically or use shared modules. An apparently spare or ignition-switched fuse position may be reserved or network-controlled. Avoid restraint, brake, steering, powertrain, high-voltage and security circuits unless the authorised wiring information explicitly supports access. Keep a circuit label and schematic with the vehicle so future diagnosis can identify the modification.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Identify | Separate RBA727 fitment from fuse format, rating and circuit | Treating all three products as one blade family |
| Inspect | Check wiper spindle and glass, or fuse socket and wiring condition | Replacing parts before diagnosing corrosion or overload |
| Fit | Control wiper spring and torque, or use correct fuse and termination | Levering on glass or increasing fuse amperage |
| Route | Protect washer hose and arm clearance, or strain-relieve breakout wire | Trapping wire under a lid or across an airbag |
| Verify | Wet-test sweep and park, or test original circuit, load and heat | Assuming movement or power alone proves correct work |
Record vehicle and RBA727 application evidence, arm position and torque for wiper work. For electrical work, record fuse-box location, original and installed rating, breakout product, conductor, load, protection and measured current. This keeps future repairs traceable without suggesting universal fitment.
Reading real Pearl Blades references
The Pearl Blades names below are examples from the current range and show why the complete description matters. They are not universal Pearl Blades recommendations and should not be treated as a fitment list. Within Pearl Blades, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Wiper Arm & Blade - Corsa | RBA727 rear arm-and-blade, exact Corsa derivative, spline, length, washer, clearance, park angle and wet test |
| Fuse - Mini Blade With Breakout Wire - 10A | 10A mini blade with breakout wire, 11 x 16mm format, original 10A circuit and supported lead use |
| Fuse - Mini Blade With Breakout Wire - 15A | 15A mini blade with breakout wire, 11 x 16mm format, original 15A circuit and supported lead use |
The product titles establish one Pearl wiper reference and two Wot-Nots-described electrical items. The collection name is therefore not used to rewrite maker identity. Exact application and electrical design remain stronger evidence than the shared page label.

- Adding an accessory without sizing and separately protecting its wire.
- Tapping a safety-critical or network circuit without approved data.
Pearl Blades questions and answers
Q: What products are on the Pearl Blades page?
A: RBA727 rear wiper arm-and-blade plus 10A and 15A mini blade fuses with breakout wires.
Q: Does RBA727 fit every Corsa?
A: No. Confirm generation, body, build and exact Pearl application before fitting.
Q: Why replace an arm and blade together?
A: The assembly can address exact arm geometry and blade interface, but spindle and motor condition still need inspection.
Q: Can the wiper be tested dry?
A: No. Wet and clean the screen first to protect rubber and glass and assess wiping correctly.
Q: What size are the breakout fuses?
A: The current titles describe 11 x 16mm mini blade products; confirm the delivered format against the socket.
Q: Can 15A replace 10A?
A: Only if the vehicle circuit specification itself requires 15A; never uprate a circuit to stop a fuse opening.
Q: What is a breakout wire for?
A: Its exact documented design may support testing, signal or auxiliary access; establish the topology and rating before use.
Q: Does fuse colour prove rating?
A: Use colour only as a cross-check and read the printed amperage plus vehicle documentation.
Q: Can an accessory run directly from the breakout wire?
A: Only after confirming source capacity, wire rating, connection method and separate protection for the new circuit.
Q: Why does a fuse keep blowing?
A: A short, overload, failed component, damaged wiring or incorrect rating requires diagnosis.
Q: Can any spare fuse slot be used?
A: No. It may be unpowered, reserved, network-controlled or connected to a safety-critical function.
Q: What should be checked afterwards?
A: For wipers, sweep, park, washer and clearance; for fuses, original function, load current, heat, warnings and secure routing.
