Wiper Motor & Linkage
Assembly Guide UK
What Is A Wiper Motor?
A wiper motor is the electric motor responsible for powering your vehicle's windscreen wipers. It converts electrical energy into mechanical motion, driving the linkage assembly that moves the wiper arms back and forth across the windscreen.
A properly working wiper motor ensures consistent wiper speed, smooth operation and reliable visibility in rain, snow or poor weather conditions, keeping you safe on the road.

What Is A Wiper Linkage Assembly?
The wiper linkage assembly is the mechanical arm system that connects the wiper motor to the wiper arms. It converts the motor's rotational movement into the back and forth sweeping motion that clears your windscreen.
Over time, linkage joints can wear out, become loose or seize up, causing wipers to move slower, get stuck or stop working altogether even when the motor itself is fine.

Bad Wiper Motor Symptoms
Not sure if your wiper motor is failing? These are the most common signs to look out for.
Wipers Moving Slowly
A noticeable drop in wiper speed often points to a worn or weakening motor.
Wipers Not Parking Correctly
If wipers stop mid-windscreen instead of returning to rest position, the motor may be failing.
Grinding Or Clicking Noise
Unusual noises from under the bonnet often indicate worn internal motor gears.
Wipers Stop Working Completely
A burnt out motor or electrical fault can cause total wiper failure.
Intermittent Wiper Function
Wipers working on and off can signal a failing electrical connection inside the motor.
Blown Fuse Repeatedly
A seized or overworked motor can draw excess current, repeatedly blowing the wiper fuse.
How A Wiper Motor Works
A simple 3-step breakdown of how power turns into wiper movement.
Electrical Signal Received
When the wiper switch is activated, electrical power flows from the vehicle's wiring to the wiper motor.
Motor Spins The Gear
The electric motor rotates an internal gear mechanism, which reduces speed and increases turning force.
Linkage Moves The Arms
The gear connects to the linkage assembly, which converts rotational motion into the sweeping arm movement.
Bad Linkage Assembly Symptoms
Even with a healthy motor, a worn linkage can still stop your wipers working properly.
Wipers Stuck In One Position
A seized or broken linkage joint can leave wipers frozen mid-sweep even when the motor runs.
Uneven Or Jerky Movement
Worn linkage joints often cause wipers to move unevenly or hesitate during their sweep.
Loose Or Rattling Noise
A rattling sound under the windscreen usually points to worn or loose linkage components.
One Wiper Works, Other Doesn't
If only one wiper arm moves while the other stays still, the linkage is often the cause, not the motor.
Wiper Motor vs Linkage Assembly – What's The Difference?
Not sure which part is causing your wiper problem? Here's how to tell them apart.
⚙️ Wiper Motor Issue
- Wipers don't move at all
- Burning smell near the motor
- No electrical response when switched on
- Fuse blows repeatedly
- Grinding noise from the motor housing
🔗 Linkage Assembly Issue
- Wipers move on one side only
- Wipers get stuck mid-sweep
- Clicking or rattling under the bonnet
- Wipers move slowly or unevenly
- Visible looseness in the linkage arms

SHOP LINKAGE ASSEMBLIES →What is the difference between a wiper motor and a linkage assembly?
The wiper motor is the electric component that generates power and movement, while the linkage assembly is the mechanical arm system that transfers that movement to the wiper arms. A fault in either part can stop your wipers from working properly.
How do I know if my wiper motor or linkage is faulty?
Common signs include wipers moving slowly, getting stuck mid-sweep, making grinding or clicking noises, working only intermittently, or not parking correctly after use.
Can a faulty wiper linkage cause the wiper motor to fail?
Yes, if the linkage seizes or becomes too stiff, it can put extra strain on the motor, causing it to overheat, draw excess current, or burn out over time.
How much does it cost to replace a wiper motor in the UK?
Costs vary depending on the vehicle make and model, but a replacement wiper motor is generally more affordable than a full linkage assembly replacement. Browse our range for exact pricing on your vehicle.
Can I replace a wiper motor myself?
It's possible for those with mechanical experience, but wiper motor and linkage replacement often involves removing trim panels and precise reassembly, so many drivers prefer to have it fitted by a qualified mechanic.
Why are my wipers only working on one side?
This is usually a linkage issue rather than a motor problem. A broken or disconnected linkage arm on one side will stop that wiper from moving even though the motor is still running.
What causes a wiper motor to stop working completely?
Common causes include a burnt out motor, a blown fuse, a broken electrical connection, or a seized linkage putting too much resistance on the motor.
Is it better to buy a wiper motor and linkage assembly together?
If both parts are showing signs of wear, or if you're unsure which one is causing the fault, buying a combined wiper motor and linkage assembly is often a more reliable, long-term fix.
Will a faulty wiper motor trigger a warning light on my dashboard?
Most vehicles don't show a dedicated warning light for wiper faults, but you may notice fuse warnings or general electrical alerts if the motor is drawing excessive current.
Do you offer a warranty on wiper motors and linkage assemblies?
Yes, our wiper motors and linkage assemblies come with a warranty for peace of mind. Check the product listing or contact our support team for specific warranty details.
