How to Replace a Windshield Wiper Motor

A windshield wiper motor is a device used to remove rain, snow, ice and debris from a windshield. Almost all motor vehicles, including cars, trucks, trains, watercraft with a cabin, and some aircraft, are equipped with such wipers, which are usually a legal requirement. If the windshield wiper motor is not functioning correctly, the signs will include the wipers only moving at one speed and stopping in the wrong place, or not moving at all.

Part 1 of 1: Replacing a windshield wiper motor

Materials Needed

  • Allen set metric and standard sockets
  • Assorted pliers
  • Assorted screwdrivers
  • Brass hammer
  • Clip remover
  • Combination wrench set, metric and standard
  • Disposable gloves
  • Emery cloth/sandpaper
  • Flashlight
  • Metric and standard wrench set
  • Pry bar
  • Ratchet ⅜ drive
  • Seal remover
  • Socket set metric and standard ⅜ drive
  • Socket set metric and standard ¼ drive
  • Torque wrench ⅜
  • Torx socket set
  • Wiper removal tool

Step 1: Remove the wiper blades. You will have to remove the wiper blades in order to gain access to the cowl, which is where the windshield wiper motor is located. Use a windshield wiper removal tool to release the tension on them so you can remove them.

The cowl might have some clips holding it down. You will need to remove them using a clip remover or another suitable tool.

Step 2: Remove the old windshield wiper motor. Now that you have gained access to the wiper motor, you can unplug it and unbolt it from the wiper gearbox assembly that connects to the wiper blades. Once you remove that, then you can remove the motor from the vehicle.

Step 3: Install the new windshield wiper motor. Remount the windshield wiper motor back onto the wiper gearbox assembly. Bolt it back onto the cowl housing and plug it back in, then reinstall the cowl plastic and the clips.

Step 4: Reinstall the wiper arms. Once you have finished installing the new motor and putting the cowl back together, reinstall the wiper arms and wiper blades onto the wiper gearbox assembly.

Tighten them down to the correct torque. Make sure you put them in the correct location so that when you activate them they will clean the windshield properly. If they don't, you can always readjust them.

Replacing your windshield wiper motor is very important because this motor operates your wipers and allows you to clean the rain, snow and dirt off your windshield. If you want to get this repaired quickly and easily, YourMechanic can send a professional mechanic to your home or office to complete the windshield wiper motor replacement for you.

Nissan Juke L4-1.6L Turbo - Windshield Wiper Motor Replacement (Front) - Abington, Pennsylvania
fantastic - i had 2 prior companies try to find and fix the wipers. Mavis had the car 8 hrs and said it was not the wiper motor or the linkage and i should take it to a dealer. Took to dealer and they said it WAS the motor or the linkage or both.. I bought a used wiper motor and hired Your Mechanic to install. Clarissa ( the mechanic) is excellent went beyond as the 1 wiper arm would not come off she got her hands into the tight space and was able to replace the part. The same repair at the dealership would have cost $1500.00 to $2000.00. THANKS so much to Clarissa!!

Dodge Ram 1500 Van V6-3.9L - Windshield Wiper Motor Replacement (Front) - Saint Petersburg, Florida
The first mechanic failed to diagnose the problem after replacing the wiper motor twice. Joe was able to determine the problem to be a ground. He had to fashion the ground wire himself since me vehicle is dated. Above and beyond. A master mechanic.

Toyota Sequoia V8-5.7L - Windshield Wiper Motor Replacement (Front) - Renton, Washington
Let me know he had to pick up some parts when he was on his way and was running a bit late, which was fine. He was very friendly and knew his stuff. Toyota had used some funky bolts so he was able to pivot and find a workaround to get the Wiper Motor off and change it out. It was great to have someone come to the house so I could get some work done while he was there and not have to go to a repair place. The cost was also about half of what I was quoted from the dealership and an independent repair place. This is a perfect service for this kind of job and I will definitely use them again!
