I have looked around the internet and forum for a guide or some info on how to fix my rear wiper motor on my 99 sport. I cannot find anything! I found write ups for zj and wjs but nothing for an xj. It is a different motor, they are pretty expensive to replace so want to avoid that. I know it works it makes noise when i press the wiper button but the shaft doesnt spin so clearly its just seized. I cant figure our how to safely get it apart without destroying it. If anyone has had the same problem and found a solution id love to hear about it!

 

On the rear if you just push the button doesn't it spray window cleaner on the glass? Geeze I have a 99 and I don't remember for sure, maybe its spray and wipe when the button is pushed.

Anyway if you don't have a Chilton's manual or one like it you do need one. But you will need to remove the inside panel that covers the rear hatch to get to the motor to check it out.

 

I already removed the motor, and when i push the button it just makes a sound like the motor is on, but the shaft doesnt spin. I know its just corroded because thats what happens to all of them but i cant figure out how to open it up, i think i need to drill out the permanent rivets holding the motor casing on.

 

It has been many, many years since I had to work on any of my rear wiper motors. But If i am not mistaken you are right about having to drill out the rivets. When you push the switch does it just make just a click like it is coming on or does it keep running and no movement of the shaft? If it keeps running without moving I would say that the gears are stripped you you may have to change the motor out. If so I would hit up your local jy and replace it.

 

My BAD

 

I actually just drilled all the rivets out and it was really gunked up in there. It actually looked like the gears were not stripped and i think the shaft was just stuck, i took it out and cleaned it all and im going to put it on tomorrow and see how it works out. Ill update with my findings if it works. I also took pics because not one person on the vast internet has a single picture or description of how to fix the late model XJ rear wiper motor, i searched for hours.

 

Yeah the pics are a good Idea. If you can you may want to post them in this thread. It may help someone in the future. I hope that it works.

 

Re-installed it and its still not doing anything, the plastic gear inside must be worn down, i thought it looked fine but i guess it isn't. It's too bad they used these cheesy plastic gears or else it would actually be a good motor.
