After researching other posts on the subject, I found that my seat problem in my 93 SSE is a bit different. Currently most of the seat functions work iin ONE direction only on the passenger seat, and only some of the functions on the driver side don't work (again in one direction). Did that make sense? The key thing though is that in all cases when I try a function that does not work, the motor seems to run but I hear a repeated clicking sound at about 2 times a second while the switch is pressed and nothing moves at all(maybe a gear is stripped?). I have not tested all the functions on both seats for fear of messing up the adjustments too much so they are "unsittable" (for example, the pass. seat only goes forward now and most of my passengers are tall! ). Any ideas? Thanks in advance.

(BTW, I was able to replace my power steering return line and cooler last month - thanks for the help).

Hmmm . . . the plot thickens. I tested all the seat functions on both sides and the drivers side seemed OK, and the lumbar functions on BOTH sides were OK (but other functions on the pass. side only worked one way), but during the course of more experimenting all seat functions suddenly stopped working and I smelled burned insulation. The power door locks quit too. I checked the fuse panel on the drivers side and the # 4 metal clad 30 amp breaker ("accessory breaker") was HOT! I pulled it, tested it and it was still shorted. It never tripped!

So .. I'm guessing I now have at least one fried seat motor and maybe door locks, too because of an apparently faulty breaker.

But do these breakers fail like that often? Seems like a huge safety issue . . .

i hightly doubt that the breaker failed....they are going to get hot when they trip....you let it cool back down and then it is functional again.....

i also doubt that you hurt any of the motors or anything like that...that is what the breaker is there for, to prevent the damage of the electronics

you have a pinched wire somewhere, causing a short...and that would also lead me to believe that is why your seats functions are not working

Well I forgot to mention that I didn't actually check the breaker until an hour after everything quit working. It was still hot! Anyway, if I do a continuity check from the seat-side breaker socket to ground, I get a short which supports your pinched wire theory. I also disconnected all three wire harness connectors under the driver seat and still have the short. Is the 12 V power supply wire somewhere else or is it in one of those harnesses? If it IS in one of the harnesses, then I would say I do have a pinched wire.

Power comes from the Orange wire and is hot at all times and should be contained in one of the wiring harnesses. It appears that the Orange wire is connected to the seat control module (located under the driver'* seat. From there, the suspect circuit for the passenger seat would be a dk blue wire at C4 in the connector on the module. The dk blue wire goes into another connector then comes out as a dk green wire to the passenger seat. If the driver'* seat is working but the passenger seat is not, then I would suspect a pinch along the dk blue to dk green connection from the module to the passenger seat if nothing is found in the Orange wire. I have the full diagnostic checks in the service manuals. if you want to borrow them, let me know.

At the worst, pull both seats out of the car and inspect them and the wiring.

During a seat conversion in 1993'* car..I was kind enough to pinch a wire under the carpet with the seat bracket to floor bolt..

This looks like a short and should be relatively straight forward to find. Being that the seat moves back and forth.. start with the wiring that could get caught in the tracks.

Thanks, folks!

I'll hopefully dig into it this weekend. It'* not a show stopper at this point. For the time being I've pulled the breaker so I'm living with manual door locks :( I really hope that smell I noticed yesterday wasn't a burnt motor winding.

Echo, you've been kind enough to offer aid several times before - thanks! I'll let you know if I need the manuals. One of these days I may take you on it up just to meet you!
