I have power seats in my '94 Cherokee Limited and both seat gearboxes have suffered the same problem, the nylon frame and bearing blocks have cracked and don't work. They are way too difficult to fabricate and I wondered if anyone has had similar problems and been able to fix them. The seat drive was changed in '95 to a totally different system and I doubt that it could be modified to be used.
The only part number I can find is for a '94 XJ 5519 5320-1 which is the whole track set and gearbox. It is strange that only one number is listed, as the right and left seat tracks are different. Anu suggestions would be great. I am only looking for the seat gearbox as my tracks are ok.
