How to Reset Your Wiper Motor to the Correct Resting Position

You just finished replacing or servicing your wiper motor, and now your windshield wipers park in the middle of the glass instead of tucking down below the hood line. It's annoying, it looks wrong, and it can actually block your view. Knowing how to reset the wiper motor to the correct resting position fixes this problem and gets your wipers sweeping and parking the way they should.

Why are my wipers stopping in the wrong spot?

Wiper motors use an internal park switch or circuit to know where to stop after each cycle. When you turn the wipers off, the motor runs until it hits that park position and then cuts power. If the motor linkage has been removed, the motor was replaced, or the assembly was disturbed, the motor's idea of "parked" no longer matches the actual wiper arm position on the windshield.

This mismatch is the most common reason wipers end up stopping in the middle of the windshield after a repair. The motor itself may work fine the problem is just alignment.

What does resetting the wiper motor actually mean?

Resetting the wiper motor means repositioning the wiper linkage and arms so they match the motor's built-in park position. The motor doesn't change you're adjusting the mechanical connection between the motor output shaft and the wiper arms. On most vehicles, this involves setting the motor to park, then attaching the linkage and arms at their correct low-point positions.

How do I reset the wiper motor to the correct resting position?

Here's the general process that works on most cars and trucks. Always check your vehicle's service manual for model-specific details.

Turn the wipers on, then off. Let the wipers complete one full sweep cycle and stop on their own. This sets the motor to its internal park position.
Disconnect the battery. Remove the negative terminal to prevent the wipers from moving accidentally while you work.
Remove the wiper arms. Lift each arm away from the windshield. Most arms pull straight up off the splined stud after you lift a small retaining clip or cap and remove a nut.
Check the motor park position. With the linkage disconnected from the motor, the motor output (crank arm) should be at its stop usually at the bottom of its travel arc. If it's not, briefly reconnect the battery, cycle the wipers once, and let them park before disconnecting again.
Reposition the linkage. Attach the wiper linkage (also called the wiper transmission or wiper crank assembly) to the motor output so the linkage arms point to the low-park position the spot where the wiper blades normally rest below the windshield.
Reinstall the wiper arms at the park position. Place each arm on its stud in the fully lowered position. The blade tips should sit at the marks or notches stamped into the windshield base molding (if your car has them). Tighten the nuts and fold the arms back down against the glass.
Reconnect the battery and test. Turn the wipers on through all speed settings. Watch that they sweep correctly and return to the proper rest position when turned off.

Is the process different for vehicles with a nut-and-bolt linkage?

Some vehicles, especially older models or trucks, use a nut-and-bolt style linkage rather than a clip-in crank arm. The principle is the same let the motor park, then reattach the linkage so the wiper arms sit at their lowest point. The key difference is that you may need to loosen a nut on the motor's crank arm rather than popping a clip.

What tools do I need?

Socket set or wrench (usually 10mm–14mm for wiper arm nuts)
Flathead screwdriver or trim removal tool (for wiper arm caps or clips)
Penetrating oil (if wiper arm studs are corroded)
Painter's tape or a marker to note the original arm position on the glass before removal

Why do wipers park wrong after a motor replacement?

Aftermarket wiper motors sometimes arrive with their output shaft in a random position. If you bolt the linkage onto the motor without first cycling the motor to its park stop, the whole assembly ends up timed wrong. That's why step one turning the wipers on and off to set the motor park position matters so much. If you skip it, you'll likely need to troubleshoot the wiper motor stopping mid-cycle or repeating the whole job.

Common mistakes that cause wipers to park in the wrong place

Not cycling the motor before connecting the linkage. This is the number-one error. Always let the motor find its park stop first.
Forcing wiper arms onto the studs in a raised position. If you push the arms on while they're above the park line, they'll stop in the wrong spot every time.
Skipping the battery disconnect. The motor can activate unexpectedly and move the linkage while your hands are in the way.
Ignoring stripped or worn splines. If the splines on the wiper arm stud are rounded off, the arm may slip under load, shifting the apparent park position over time.
Confusing a motor problem with an alignment problem. If the motor won't park at all it just runs continuously or stops randomly you may have a wiper motor failure rather than a simple alignment issue.

Can I adjust the park position without removing the wiper arms?

On some vehicles, you can loosen the wiper arm nuts just enough to reposition the arms without fully removing them. Slide each arm down to the correct resting spot and retighten. This works when the motor and linkage are already timed correctly but the arms were simply installed at the wrong angle. However, if the linkage itself is mispositioned, you'll need to go through the full process above.

How do I know where the correct park position is?

Most vehicles have small triangle marks, notches, or dimples along the base of the windshield where the blade tips should rest when parked. If your car doesn't have visible marks, check the service manual or look at photos of the same model online. A general rule: the driver-side blade tip should rest about 1 inch above the base of the windshield, and the passenger-side blade should sit at a matching or slightly lower height. Some styles use a custom typeface similar to Bebas Neue for model-specific windshield markings, but most use simple stamped indicators.

Quick tips for a clean reset

Use painter's tape on the windshield to mark the correct blade positions before you start, so you have a visual reference when reinstalling arms.
Work in a clean, dry area. Grease or dirt on the spline connection can cause slipping.
Apply a small amount of dielectric grease to the splines before reassembling to prevent future corrosion and seizing.
Torque wiper arm nuts to spec. Under-tightening leads to slipping; over-tightening can strip the studs.

What should I do if the reset doesn't fix the problem?

If you've followed every step and the wipers still park wrong, the issue may be inside the motor itself. A worn or damaged park switch inside the motor housing won't signal the motor to stop at the right point. At that stage, motor replacement is usually the fix. Test the motor by grounding the park circuit wire (per your service manual) to see if the motor responds. If it doesn't, it's time for a new unit.

Quick checklist: Reset your wiper motor park position

Cycle wipers on then off so the motor parks internally
Disconnect the negative battery terminal
Remove or loosen wiper arms from studs
Verify the motor crank arm is at its full park-stop position
Reattach linkage to motor with linkage at the low-park position
Reinstall wiper arms at the correct parked height
Tighten arm nuts to spec
Reconnect battery and test all wiper speeds
Verify blades park at the windshield base marks

Mark your windshield with tape before you start, let the motor park before you connect anything, and always test every speed setting before calling the job done. If wipers still behave oddly after a proper reset, the motor's internal park circuit may need closer diagnosis.
