I understand they are difficult to repair. I have mine apart, but I haven't started the cleaning process.

?? My left seat forward failed - would only go back. Removed cover plate, pulled switch, opened, cleaned, reassembled, worked fine. No problems.

I took mine apart and cleaned all contacts with WD-40 put them back together and everything worked. Still working a year later.

You have nothing to lose, they arn't working now.

Good Luck.

Thanks. I'll give WD-40 a try.

These switches are essentially the same as the window rocker switches in the center console.

My window switches weren't working either. They were easy to repair. Pull off the top, use a regular pencil eraser to brighten up the contacts, apply a bit of electronic contact lube and reassemble.

I bet WD-40 is a pretty good contact lube.

Have at it.

What can I do about a noisy seat motor? By the way, I think all of you have given excellent advice about the switches.

Jim,

Obviously you can see that your seat switches are different than the window, S/R, rear wiper. The 4-way seat switch is more complex. Make sure you keep track of the springs and ball bearings that come out when you open them up. The key is like all the switches, you want to file off the carbon buildup on the contacts. Putting it back together is slighly tricky with the springs and balll bearings but doable. It will be like new when you are done.

I cleaned mine with spray electric cleaner and used the grease for spark plug terminals where the ball bearings contact the contacts.

I'll test it sometime this weekend

This isn't as obvious as you might think.

The early 928 electric seats have three switches each that are identical in every way to the window switches. They have no four-way switch.

I don't know when they went to the four-way switch seats.

Jimbo

The cleaner didn't work...I had to scrape the carbon off of the contacts.

Getting the ball bearings to stay in place was a pain otherwise it went well. I was also able to repair a second switch W/O removing it.

To keep the little buggers from escaping, you can locate the ***** on the springs, for reassembly, with a little vaseline.

Also, note that the distal edge of the switch contact support (the moving part) extends a little past the contact. On my window switches, this little bit of metal hung up on the plastic lip at the edge of the switch-base, preventing contact without HUGE force on the rocker. I Dremmel-trimmed the plastic lip about 25% and it's all good, now.

Jimbo

Brian,
I used silicon lube...next time I'll go with vaseline.

Since they sell for $60+ it was worth it to repair rather than replace.

I wish this thread was up before I took mine apart and spent hours chasing after springs and ***** in my garage floor... ended with ordering new ones of course
Glad this tip is now out, though!

Jim:
I could have said "use K-Y Jelly" but you'd probably have accused me of something other than being a medic!! <img border="0" alt="[hiha]" title="" src="graemlins/roflmao.gif" />

Plus, credit where credit is due: <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" />
Most of my info has come from the Rennlist, either here on the Forum or from the e-mail one-list. Somebody named Wally <img border="0" alt="[king]" title="" src="graemlins/r.gif" /> communicated a lot of it. I just happen to be here quite a bit as I try to figure out how to reassemble my engine compartment, in the face of apparent Alzheimers! <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />

The best tip for repairing switches is to take them apart inside a clear plastic bag. Sure saves hunting for invisible parts on a dirty floor - or even worse, in the grass and dirt!
