Wiper Motor Diagnosis & Replacement in South London
Mobile windscreen-wiper fault diagnosis and suitable motor replacement, with electrical supply and linkage faults checked first.
Dead or erratic wipers do not always need a motor
A blown fuse, weak earth, damaged wiring, failed switch, control-module issue or seized linkage can stop the wipers or make them run slowly. SP88 tests the circuit and mechanism before recommending a motor.
Linkage movement
A seized spindle or disconnected linkage can overload a good motor or stop the blades moving.
Parking and speeds
Incorrect parking, missing speeds and intermittent operation help separate motor, switch and control faults.
Safety first: Wipers are essential for visibility. Do not drive in rain or poor conditions if they do not clear the windscreen reliably. Stop if the linkage is loose or the blades can strike trim or bodywork.
How SP88 approaches the job
Reproduce the fault
Check speed, intermittent and park behaviour where safe.
Test the circuit
Confirm supply, earth and command before condemning the motor.
Inspect the mechanism
Check accessible linkage and spindles for seizure or damage.
Replace and verify
Fit the matched motor when appropriate, set the park position and test operation.
What replacement includes
- Diagnosis of accessible wiper power, earth, fuse and control inputs.
- Inspection of visible linkage movement and spindle condition.
- Suitable front or rear wiper-motor replacement when the motor is confirmed faulty and access allows.
- Correct park-position setup and functional checks after fitting.
Front and rear motors differ, and connectors, control electronics, park positions and linkages vary by model. Compatibility is confirmed from vehicle and fitted-part details.
Mobile or workshop?
Many wiper-motor and linkage faults are mobile-suitable. Restricted scuttle access, seized assemblies, water-damaged control units or work involving bonded glass and camera systems may need workshop or specialist support.
Areas covered
Wallington, Sutton, Carshalton, Croydon, Purley and nearby South London and Surrey areas, subject to access and job suitability.

Questions customers ask
Why do the wipers stop in the wrong position?
A motor park circuit, linkage alignment, loose arm or control fault can cause this. The park position should be diagnosed before parts are ordered.
Can a seized linkage damage the motor?
Yes. Excess resistance can slow, overheat or overload the motor, so the mechanism must be checked with the electrical fault.
Do rain-sensor faults mean the motor is bad?
No. Rain sensors and automatic-wiper commands are separate from the motor itself and need the appropriate diagnostic checks.
