so after my wiper motor ordeal earlier this week i decided to create a writeup showing how it was replaced since i haven't really had much to contribute to the jeeping community thus far. this may be easy, but when i was looking for info/tips before i did it i didn't see one out there... so, here it is. some pics were taken with a blackberry, some with camera. this is for my 2000.
as i said, this is a very easy replacement. i was fully expecting something to go wrong and for it to take 2x as long, but somehow it went smoothly. about a half hour start to finish with taking pictures. click pictures to enlarge.
* phillips head screwdriver
* fladhead screwdriver
* 10mm socket/6" extension
* 1/2" open ended wrench or socket (not pictured)
* channel lock pliers
remove wipers. pry on tab under the wipes with flathead screwdriver until it pops out this far, otherwise it won't come off. the thing that slides actually contacts the body of the wiper arm so i had to fight it to get it off
remove the 4 phillips head screws from the top of the cowl and one from the center vent
open the hood and peel back the hood/cowl trim to access 2 more phillips head screws (one on each side. this is just the passenger side). these might give some trouble. they screw into a metal clip/nut that might become rusty over time. mine had rusted out so i had to pry on the underside of the screw head to put pressure on the nut to prevent it from spinning. (don't mind the exposed wire off the ecu, that's fixed)
shut the hood and take off the cowl. i found it easiest to pull up from the front/hood side first.
with the cowl off you have easy access to the wiper motor from the drivers side. on my plug there was a red safety piece on the plug. pry that up and unplug the motor. there's 3 10mm bolts holding the wiper motor/arm assembly in. take those out and remove the whole assembly.
there are 3 10mm bolts holding the motor to the bracket, and one 1/2" nut holding the arm assembly onto the motor shaft. i found it easier to remove the nut from the arm before removing the motor to bracket bolts so the motor wasn't wobbling around. i also used the flathead to prevent the arm from moving when trying to loosen the nut.
the plug on the motor is attached to the bracket. i got the flathead under the plug and just pried it up and out. i then realized that there is a track sort of thing under it that the plug can slide off of. either way, that has to come off.
OLD VS NEW:
rubber boot peeled off. i could almost put a screwdriver right through the wall... very rotted out.
reinstall is the reverse.
*get the motor bolted to the bracket with the 3 10mm bolts.
*attach the wiper arm (the shaft is keyed so it will only fit on 2 ways).
*attach the plug to the bracket.
*get the assembly put back into the jeep.
*secure the 3 10mm bolts.
*plug the harness back in.
make sure to slide down the red safety clip. i didn't and mine came unplugged in 1 day
*test the motor with the cowl off before putting the cowl back on.
*put the cowl back on.
*get the 7 phillips head screws put back in.
*reattach the wiper arms and you should be done.
