The shaft has a gear on the end that is engaged with drive motor inside. It won't turn now. Take it apart, it's an easy procedure. I've done it four times on different Jeeps, always worked (100%).

Im pretty sure i already stated this in another wiper motor thread with you. If it doesnt work now and you attempt the fix and it still doesnt work what are you out? Just some time and a little effort. Mine was seized for years or so i thought. Pulled it and found cracked solders easy as that. Worst case scenario is you try to fix it and still doesnt work. No biggy. Not being critical just saying give it a try.

It was seized so bad that the shaft broke completely off still in the sleeve must have been that was for a VERY long time, it was actually full of rust around the yellow gear. I was told it came from down south near the salt water in or around vancouver area when I bought the jeep.

Thanks OP for the post. Figured it was a shaft issue and will find out over the weekend.

Had similar problem with a 98 Nissan Pathfinder. The fix was easier as it didn't involve the circuit board removal.

Always used Nev-R-Seize on the shaft after.

My rear wiper has never worked until today. Cleaned the shaft as per the OP's instructions although I used a steel brush wheel to do it, worked like a charm! Regreased everything and put it all back together, and BAM I've got rear wiper action...Also resealed the gaskets to avoid having to do this again, even though it was actually pretty easy....
Great write up!

Now I just gotta get my wiper blade back from my ol' lady, since she talked me into letting her put it on her CR-V

Hello there, first of all, really nice write up, helped a lot of owners and saved them few $. Actually I applied the same procedure before reading this thread but had some problems which are mentioned in this thread as well, couldn't figure out how to resolve, but 2 days back, it just worked and I found the secret, thought of sharing as I read there are many who followed the procedure and ended up with single spin or not spinning at all.
It's true that it is good to "mark" the gear inside, but it is not that difficult to find the correct placing. I never marked the thing, and I faced the same problem of single spin. Finally I gave up on that and reassembled the motor and the back cover. After packing everything, when I started the jeep, i noticed it working problem free.
So the trick was that the motor would not work untill you close the trunk door, As far as the trunk is open, the sensor will stop the motor from spinning, and that was the mistake I was doing that after cleaning the whole thing, I was testing it by just connecting the wire (trunk door opened), so all you guys who have gone through this procedure and are still facing problems, remember to close the trunk before you give it a try
Hope this helps!

For gomes512,

Great write up! However, I missed the part about marking the wheel before taking it out of the shaft, and now I can't seem to put it in properly. Do you have a suggestion as to how I can align the wheel so it will fit properly? Thanks!

EDIT: I also have tried plugging it in while the trunk door is shut. Everything is working except the wheel will not spin in the shaft.

It's been so long since I did this, you have to look at the gear face (it has the contact) and the arms on the motor body. Try different start positions by moving the gear forward or back a few notches.

Big thanks gomes512,
BUT, my other half own a Jeep WJ Grand Cherokee and I joined here on her behalf, we're from the UK, Scotland Perth to be exact and I own another vehicle and belong to another forum and sadly i have the same issue here!
The guys in the know will stay in the know because you missed a major part of this operation.
I dont have a clue how to get in to the back panel of the tailgate and as wondrous as your post is, I still have to do some studying to get to where you got before this amazing post!
My Lady is agog to find she is stressed to worry over a lack of rear wiper as she has a lot of mileage to do and the rear wiper has been playing up!
Basically, it goes 1 wipe then stops, sometime on the other side or just one wipe then it parks up.
I do not plan on opening up the tailgate but will employ part of your great post but i am not electrically qualified or trained to do what you have done with the circuit board, but hey judging by the overwhelming gratitude displayed by fellow members, you must all be!! (No engineer jokes here! )

Thank you and I mean it, a big help would have been a link to "opening up the tailgate", but it must be difficult as there are so may different models concerned so I empathize greatly!!

So I end in saying a big thank you none the less! Surely my Girl has gone mad trying to find a cure, OR a new rear wiper as she has looked for a few hours and has been totally frustrated by the lack of info in general on the net and especially in the UK!

And to our American friends please stay as you are, great going thanks! we DO have friends, thank you !
PS and a big PS too, does anyone have the part number of the Grand Cherokee WJ 2003 2.7crd rear wiper motor? Any onfo much appreciated!! Thanks in advance, Stu

I had to order a new motor too, cause the old one was completely seized up.
