Purchased a used '94 convertible and soon discovered that the driver's side power seat did not have full functionality, sounds like stripped gears on the front up-down adjustment. (i.e. motor runs, but seat does not adjust).

I see these pwer seat mechanism are available for about $200 plus the core, my question is are there any on line repair and replace instructions without having to invest in expensive repair manuals?

Does anyone have the removal, repair, replacement experience and willingness to share their know how via the forum?

Thanks in advance for your advice.

Received several replies from another forum and after removing the seat discovered a disengaged motor drive cable and a broken neoprene bushing. Designed a replacement neoprene adapter, produced by a local machine shop, installed without necessitating seat removal, and presto, seat control and movement is good as new! Design and photos available upon request.

Hello

The driver’s side seat on my C4 Vette did not adjust, or tilt, up or down when I first purchased the car.

After removing the seat and inspecting the drive mechanism, I discovered that there are plastic-neoprene bushing-housings, one on either side of the seat drive mechansim, which are connected by a drive cable which in turn runs through a rubber tubing-housing. This rubber tubing-housing with the cable inside connects the opposite side drive gears for the up-down (or front and back) adjustment function. One end of the plastic-neoprene bushing on my driver's side seat was broken and the square drive end of the cable had become disengaged, therefore no longer able to drive the gearing mechanism.

Although, the shaft of the plastic-neoprene housing was sheared off and could not be removed from the rubber tubing-housing without absolute destruction, nevertheless with the seat removed, I was able to reinstall the drive cable without the benefit of the rubber tubing-housing and reinstalled the seat and all six adjustments worked fine.

At the time, with the reinstalled seat, I continued to be concerned about possible lubricant leaks and potential recurring disengagement, and then the following repair idea came to me.

The photos show what the trouble was with the up-down adjustment drive bushing on the driver’s seat and he solution I used to resolve the problem.

The plastic-neoprene bushing was broken and the drive cable had disengaged. So I designed a replacement adapter and took the drawing to a local machine shop and asked the owner if they could make an adapter. One of his machinists did so, even out of the same plastic-neoprene material, and I installed it without having to remove the seat again. It cost me a dozen “Krispy Kreme” do nuts. Now the cable is held in place by the adapter and the up-down switch adjusts the seat like it was never broken.

It helps to have a friendly machinist to aid with this kind of replacement repair!
