Well, I'd love to do a search on this, but it appears that the forum's search feature is broken in that it won't return hits with both the keywords "seat" and "heat" at the same time!

Anyway, I have a '94 FWB and it appears that none of the seat heat elements work. I hear the click of the relay when I turn it on "high" but nothing really happens. Anyone have any tips on where to look, hopefully something broken that's a moderately easy and inexpensive fix? I hope not to replace the heating elements. -- I imagine they are hard to find.

I asked this question long ago and I was told "you have a factory service manual, why don't you look at that??"

Well, lo and behold, they were right. The FSM has an EXTENSIVE proceedure to troubleshoot the seats. I will post up some pics of these pages in a minute.

I haven't had a chance to troubleshoot my own, yet!

Here you go pics added as attachments:They should be what you and I both need to figure out why the heat function doesn't work anymore on our 94 FWBs.

Thanks for the post BC, very useful.
I discovered that one of the wires on the pass. seat connector had come disconnected, so I soldered it onto a new connector and presto! passenger side works. The driver's side is another story.
I measured resistance across the temperature sensor (test #4) and came up with 5900 ohms. This is out of the range of 5000 but it may be because my DVM is a cheap inaccurate POS. Then I moved to test #5 and got infinite resistance. This tells me I should replace the back cushion element. Where can I get one of these; does anyone sell them new?
Then again, I may have been measuring the wrong side of connector #335. I was probing the female side, and it looks from the picture that the male side is the one that goes to the back element. Next time I get home I will double check....
