How Do You Reset a Windshield Wiper Motor?
Most wiper motors lack a reset button. Fix parking issues by clearing obstructions, exiting service mode, and aligning arms or linkage. Learn step-by-step troubleshooting, safety tips, and when initialization is required to restore proper wiper function.
Quick Answer
Most cars do not have a windshield wiper motor reset button. Start by clearing snow, ice, or debris and checking whether the wipers are in blade-change mode. If their path is clear, wet the windshield, briefly run the wipers, then switch them off and let them return to rest. If they still stop incorrectly, the arms, linkage, or motor’s parking system may need repair.
Safety note: Keep hands and tools away whenever the wipers have electrical power—they can move after you select OFF. Before removing arms or touching the mechanism, disconnect power as instructed for your vehicle. Never force the arms across the glass. Stop testing if they collide or hit the trim, and do not drive if you cannot keep the windshield clear.
Where Is the Wiper Motor Reset Button?
On most cars, there isn’t one. You may find a blade-change setting or a specific sequence using the wiper stalk, but these controls are different from a reset button on the motor.
The right fix depends on what happened: wipers left raised after a blade change, arms installed in the wrong position, and wipers that suddenly stop working require different checks.
How Do You Get Your Wipers Back to Their Normal Position?
1. Clear anything blocking the blades
Park safely and switch the wipers and ignition off. Check for packed snow, ice, leaves, or a blade caught against the trim. Thaw frozen blades completely before trying them again.
If the wipers stopped while struggling against snow or ice, leave them switched off while you clear the obstruction. Some systems temporarily shut down under excessive load. If they repeatedly stop, move slowly, or produce a burning smell, stop using them and arrange a repair.
2. Check whether blade-change mode is active
Did the wipers stay upright after you changed the blades? They may still be in service position, which keeps them accessible above the hood.
Look under “wiper service position” or “changing wiper blades” in your owner’s manual. Carefully lower any lifted arms onto the glass before following the exit instructions. Your car may use the stalk, an ignition sequence, or a touchscreen setting; the sequence varies by model.
3. Run a brief wipe cycle
If the blades are attached correctly and their path is clear:
- Wet the windshield so the blades do not drag across dry glass.
- From the driver’s seat, switch the vehicle’s power on as needed for normal wiper operation.
- Briefly select low-speed wiping, then move the wiper control to OFF.
- Leave the vehicle powered long enough for the blades to finish their movement and return to rest.
If they return normally, check another few cycles. If they hit each other, strike the cowl, or travel beyond the glass, stop immediately. Repeated cycling can cause further damage.
4. Use the stopping pattern to choose your next step
| What You Notice | What to Do Next |
|---|---|
| Both blades stop at the same incorrect position each time | Have arm and motor-to-linkage alignment checked, especially after recent repairs. |
| They stop wherever you select OFF | Have the motor’s parking function and its electrical connections tested. |
| One arm stays still or moves out of sync | Check for a loose arm connection or damaged linkage before buying a motor. |
| Neither blade moves | Check obstructions and the correct fuse, then arrange electrical and mechanical diagnosis. |
Why Do the Wipers Keep Stopping in the Wrong Place?
Your wipers need to know when they have reached their resting position. Many systems use an internal park switch or position signal to keep the motor running after you select OFF, then stop it at the correct point.
If that signal or its electrical supply fails, the blades may stop halfway across the windshield. If the motor stops correctly but the arms are attached at the wrong angle, the blades can consistently park too high or low.
A loose or damaged wiper linkage can also change their movement. This mechanism connects the motor to the arms. If one blade stops, the sweep changes between cycles, or you hear clunking beneath the windshield, have those connections inspected.
What If the Problem Started After Replacing the Motor or Arms?
Return to the installation first. The motor needs to be at its correct parking position before the crank, linkage, and arms are aligned as specified for your car.
- After removing only the arms: Check their position against the vehicle’s alignment marks or specified measurements. Inspect the mounting splines and fasteners if an arm has slipped.
- After replacing the motor or disconnecting its crank: Have the motor’s park position and crank-to-linkage alignment verified before repositioning the blades.
- After work on an electronically controlled system: Check whether your model requires initialization or synchronization, sometimes using a scan tool.
If you are doing the work yourself, use the instructions for your exact vehicle, isolate power before handling the mechanism, and use the specified fastener torque. Do not guess the crank angle or force the motor shaft to turn.
When Do You Need a Repair Instead of a Reset?
A reset cannot restore a damaged connection or worn component. Arrange diagnosis if the simple checks do not work, the fault returns, or the wipers behave unpredictably.
- A fuse blows again: Stop replacing it. A short circuit or jammed mechanism may be responsible. Never fit a higher-rated fuse.
- The motor makes noise but the blades do not move normally: Check the drive connections and linkage for damage or binding.
- The motor is silent: Its power supply, ground, switch commands, and connections need checking before replacement.
- The parking function has failed inside the motor: A replacement wiper motor may be required once the fault is confirmed.
If worn linkage is the cause, the wiper linkage selection guide explains what to compare when choosing a replacement.

FAQs
Will disconnecting the battery reset the wiper motor?
Usually, it will not fix the problem. Disconnecting the battery does not correct arm alignment, repair worn linkage, or restore a failed park switch. Follow a battery-disconnection or relearn procedure only if it is specified for your car.
Can I push the wipers back down by hand?
No. Forcing attached arms across the glass can damage their connections or drive mechanism. Exit service mode using the controls, or have incorrect alignment repaired.
Will new wiper blades fix incorrect parking?
No. New blades can improve wiping quality, but they do not correct motor parking or arm alignment. Check blade fitment if the problem began immediately after changing them and they now catch or collide.
Can I reset the rear wiper the same way?
Not necessarily. Rear wipers often have a different motor and resting position. Check your owner’s manual and use the rear-wiper instructions for your vehicle.
