How to Reset Windshield Wiper Motor to the Correct Resting Position

Your windshield wipers should park neatly at the bottom of the windshield when you turn them off. But if they've stopped halfway up the glass, frozen at an awkward angle, or landed in a spot that blocks your view, the wiper motor's resting position is off. This isn't just annoying it can be a real safety issue, especially in rain or snow. Knowing how to reset the windshield wiper motor to its correct resting position can save you a trip to the mechanic and get your wipers working the way they should.

Why Did My Wipers Stop in the Wrong Position?

There are a few common reasons your wipers end up parked in the wrong spot. The most frequent cause is that the wiper linkage has slipped on the motor's pivot shaft. This usually happens after someone removed the wipers for replacement or cleaning and didn't align them properly when putting them back. It can also happen if the wiper arm splines strip from age or force.

Other times, the issue comes from the wiper motor's internal park switch wearing out, which tells the motor when to stop. If you're seeing your wiper motor stopping mid-windshield, the park switch inside the motor could be the culprit.

A third possibility is that the motor itself was replaced and installed without being set to the park position first. This is a surprisingly common mistake, even at some shops.

What Does "Resetting" the Wiper Motor Actually Mean?

Resetting the wiper motor means setting the motor's internal park position so that when you turn the wipers off, they return to the correct resting spot at the base of the windshield. It involves either adjusting the linkage, repositioning the wiper arms on their splines, or in some cases, cycling the motor through its range so the park switch can re-learn where to stop.

It's not the same as replacing the motor you're just making sure everything lines up the way the factory intended.

How Do I Reset the Wiper Motor to the Correct Park Position?

Here's a straightforward process that works on most vehicles. Always consult your owner's manual or a repair manual for your specific model, since designs vary.

Step 1: Turn the Wipers On, Then Off

Turn your wipers on to their lowest (intermittent or slow) setting, then immediately switch them off. This triggers the park circuit and tells the motor to return to its resting position. Watch where the blades stop.

Step 2: Turn Off the Ignition While Wipers Are Moving

If the blades are stuck in a mid-cycle position, turn the wipers on and then kill the ignition while the wipers are moving. This will freeze the motor in place and allow you to check the linkage and arm positions without the blades snapping back to the (wrong) park position.

Step 3: Remove the Wiper Arms

Lift the wiper arms away from the windshield. Remove the small cover or cap at the base of each arm where it attaches to the pivot stud. Use a socket or wrench to remove the nut holding the arm in place, then gently pull the arm off the spline. If it's stuck, a wiper arm puller tool can help without damaging anything.

Step 4: Re-engage the Park Circuit

With the wiper arms removed, turn the ignition back on and activate the wipers briefly, then switch them off. Let the motor run until it clicks into its park position. You'll hear the motor spin and stop that's the internal park switch doing its job.

Step 5: Reposition the Wiper Arms

Place the wiper arms back onto the spline studs in the correct resting position. On most vehicles, the driver's side blade should rest about one to two inches above the bottom of the windshield cowl, and the passenger side should sit symmetrically. Some vehicles have alignment marks or reference points on the windshield or cowl to guide you.

Tighten the mounting nuts firmly but don't overtighten you don't want to strip the splines.

Step 6: Test the Wipers

Turn the wipers on through all settings low, high, intermittent then switch them off. The blades should sweep normally and return to the correct parked position at the bottom of the windshield. If they do, you're done.

What If the Wipers Still Park in the Wrong Spot?

If you've repositioned the arms and the blades still won't park correctly, the problem might be deeper. A worn internal park switch in the motor means the motor doesn't know when to stop. In that case, the motor assembly needs to be replaced or rebuilt. You can read more about diagnosing wiper blades that are stuck or not moving to narrow down the issue.

Also check the wiper linkage itself. If the ball joints or pivot points in the linkage are worn or disconnected, the motor may be working fine but the force isn't reaching the arms properly. A loose or bent linkage rod will throw off the park position no matter how many times you reset the motor.

Can I Avoid This Problem in the Future?

Yes. A few habits go a long way:

Never lift wiper arms aggressively in winter. Forcing frozen blades off the windshield can bend the arms or damage the splines.
Mark the arm position before removal. If you're replacing wiper blades or arms, put a piece of tape on the windshield to mark where the blade rests before you take anything off.
Don't force the arms onto the studs. The splines are designed to only fit one way. Forcing the arm at the wrong angle will round off the splines over time.
Inspect the wiper system periodically. Catching early signs of wear prevents bigger headaches. Our guide on signs your wiper system needs maintenance covers what to look for before things go wrong.

What Tools Do I Need for This Job?

You don't need much. Here's the short list:

A socket set or wrench (usually 13mm or 15mm for wiper arm nuts, but it varies by vehicle)
A flathead screwdriver or trim tool to pop off the arm cap covers
A wiper arm puller (optional, helpful if arms are seized to the splines)
A piece of tape or marker to note blade positions before removal
Your vehicle's repair manual or a quick check on a trusted site like Montserrat for model-specific torque specs if needed

What Mistakes Should I Watch Out For?

A few common errors trip people up:

Reinstalling the arms while the motor is mid-cycle. Always let the motor complete its park cycle before putting the arms back on. Otherwise you're just rebuilding the same problem.
Overtightening the arm nuts. This strips the soft metal splines on the pivot stud, and then the arms won't hold position at all.
Ignoring a grinding or clicking noise from the motor. That sound often means the internal gears or park switch are failing. Resetting the position won't fix worn-out internals.
Forgetting to test all wiper speeds. Sometimes the park position looks fine on intermittent but drifts on high speed. Test every setting.

Quick Checklist: Resetting Your Wiper Motor Park Position

✅ Turn wipers on, then off observe where blades park
✅ If blades park incorrectly, turn ignition off mid-cycle to freeze motor
✅ Remove wiper arms by taking off caps and loosening nuts
✅ Re-engage park circuit by turning wipers on (without arms) and letting motor cycle to park
✅ Reinstall arms at correct resting position using alignment marks
✅ Tighten arm nuts to snug don't overtighten
✅ Test all wiper speeds and confirm blades park correctly every time

Next step: If your wipers still won't park properly after following this process, the motor's internal park switch is likely worn. At that point, replacing the wiper motor assembly is the fix. Before you buy a replacement, check the linkage and connectors to make sure you're not replacing a good motor when the real problem is a loose linkage rod or corroded plug. Download Now
