Wiper Motor Removal Procedures
I had to replace my wiper motor, and thought I’d post my procedures. I’ll post up the pictures tonight. The whole process wasn’t very hard, but the wiper arms were a real bear to get off the arm studs.
Tools Needed:
Hammer
Needle Nose Pliers
Small Common Screwdriver
Regular Common Screwdriver
T20 Torx
T30 Torx
Small Puller (I used a battery terminal puller)
Ratchet
Socket (10 MM Metric)
Socket (1/2 SAE)
5 inch extension
Parts Needed:
Wiper Motor
Removal
1. Remove 25 amp windshield wiper fuse (fuse 10) in the passenger’s side fuse box.
2. Disconnect the windshield washer hoses from the wiper arms.
3. Remove screen tray connectors by prying the center the center section of the connector with a small screwdriver; this center section spreads the connector feet keeping the connector locked in. Take needle nose pliers and remove the outer casing.
4. Use a small screwdriver and remove windshield wiper arm nut caps. Use caution not to mar the wiper blade finish. The nut is very tight, penetrating oil sprayed onto the connecting nut will facilitate the nut removal. Remove the ½ nut underneath the cover.
5. Remove the wiper arm by using small puller, to press the wiper stud and pull up the wiper arm.
6. Carefully pull the wiper valley cover tray away from the windshield, start by pulling the corners free, where there is very little clearance between the windshield and the top corner of the fenders. Work from the corners to the center section.
7. Flip the cover over and rest on top of engine, be careful not to break the washer hose etc. This will expose the wiper transmission linkage, and the wiper motor attached to the linkage in the drivers corner of the wiper valley.
8. Remove the two 10 MM wiper transmission bolts on driver’s side.
9. Remove the 10 MM wiper transmission bolt on passenger side.
10. Remove the T30 Torx screw and lift the motor arm that connects the wiper transmission to the top of the motor.
11. Remove the three T30 Torx screws that hold the motor to the wiper transmission.
12. Carefully work the transmission free to expose the wiper motor, and move away from wiper valley. Use care not to damage the transmission arms during removal or storage.
13. Take wiper motor out of valley and turn the motor over, use a small common screwdriver to depress the locking catch, and remove the electrical plug from the motor.
14. Clean any debris out of the three rubber drain channels (udders).
15. Remove T20 Torx screw, and separate the wiper motor plate and rubber shield from the wiper motor.

Great job and damn well documented .
Did you modified the outlet of the three udders? Imo they are miserable constructed.
My wiper motor was awash and I found the three rubber drain channels (udders) blocked with mud and leaves. The lower port of the udders are miserable constructed.
I enlarged the outlet yesterday. Now the water and dirt will be will be sluiced down.

Excellent write-up!!! I had to stumble through this last year, and this would have been very helpful!! Turned out the cam on top was not installed correctly and my wiper motor was actually good! So pay attention to how the cam is oreinted before you remove it...
FYI I believe the closed end design on the udders is to keep rodents out of the blower motor/cabin...

I don't think they go to the park position, they just cycle and slam against the stops. They wont go to the park position no mater where I put the wipers. Another funny thing is when the delay is on, they pause in the middle of their travel for a second then start moving again

Taking the motor out looks straight forward, but how do you re-attach the drive linkage so that the wipers stop in the right place? I think I saw a post somewhere on how to synchronize the cam. It would be good to get that information together with this so people have the complete job.

You should easily be able to get those at your dealer - probably in stock and probably overpriced.
I would add to this nice write up, that there is one of the plastic pop-fasteners that is different than the other four - it is located right at the passenger side hump molded into the cowl cover.
Also, I was able to just soak the wiper arm bolts with PBlaster and then firmly grasp each arm and wiggle it up and off - protect the paint of the fender on the drivers side for safety.
Finally, try to get your hands under the cowl and push up on the pop-fasteners while squeezing them underneath to get them up and out of the holes.
best regards -

As far as I know,,,there there to allow water OUT and to keep things from getting in. From my expierence,,,, things (mice) can get in even if the utters are in place. Yes, you can yank them. That doesnt mean that the holes they leave still cant get clogged. Check them every once in a while!!
