Just picked up a 06 coupe. 26K miles. Was trying to program the auto memory function, now the seats dont work.
Before I start trying to change fuses, etc. Is it possible I shut something off?
Anybody with any experience with this?

"The seats don't work."

Are you saying that the manual mode doesn't move the seats or just the automatic mode?

If the memory button is not functioning, then you have a problem. If the power seat buttons don't do anything, that is a problem. I'd check the fuse if it was my Vette.

Hi

Thanks for the responses.

Neither the manual not the memory relating to the power seats are working.

I was trying to set the memory features when I noticed the seat functions arent working. I was doing this late and decided to call it a night and on a whim thought I'd check to make sure there wasnt something I'd pressed to desable the seat.

My first suspect is the fuse which I'll check tomorrow pm. But if that was the case what would cause the fuse to blow?

Also, the sequence the addresses the seats, etc., doesnt appear which seems odd. I'm not familiar with C-6 stuff so I'm likely missing something. (Previously owned c-4 and c-3) Any input would be appreciated.
Thanks.

Is the telescoping steering column also not working?

Might be 2 fuses involved. Plus, you might as well check the seat heater fuse. See pgs 5-94 to 97 in the owners manual: http://www.gmpartshouse.com/download...06corvette.pdf

Notice that there should be some spare fuses & a fuse puller on the passenger footwell fuse block.

The real cause might be damaged wiring under the seat. Take a look with a flashlight. But you might have to unbolt & lift the seat to get a good look... much easier if you have a 2nd person helping.

Thanks for your response.

I've had to put the issue aside since I first posted it. I'll be back out with my Vette Sunday afternoon.

I havent used the telescopic steering wheel yet - the position it was in was fine. I did identify one one fuse and it seemed hot at the time.

I did get a manual so I'll check out your reference and go through your suggestions. I also have an inexpensive Harbor Freight code reader and I'll see if there are any DTC codes.

Thanks for all your help.

The usual suspects for this in a C-5 would be the fuses and the seat to car connectors under the driver's seat itself. I'm not sure about the C-6 yet although there has to be the same items of course. Is there any evidence of water on the carpet under the seat? The SCM controls the telescoping steering wheel and seat memory functions.

vetadmiral

I've done some more sluthing. The lumbar controls work; the telescoping does not. None of the other seat controls work. The automatic adjustments dont work. The fuse that controls the non-working stuff is hot to the touch. I thought I try to replace it but without luck for now. The local Checker and Auto Zone do not carry it. I went to a local Chevy dealer - not in stock and had to order it. Wait for a week. That's when I found out it was a breaker. I did a continuity check on the breaker and it shows about 1 ohm.
Under the seats appears to be clean. The wires are connected, not kinked or hot.
I removed the breaker as I didnt like keeping something burning to the touch in place. After the breaker cooled off (a couple of hours to make sure), I stuck it back in and the passenger seats worked for a few minutes. Then the breaker got hot again and everything quit working. I took the breaker out.
Any suggestions? Or am I doomed to a dealer visit?

dgrant3830

Sounds like a bad breaker or one of the seat motors is not shutting off therefore causing too much current to be drawn through it, therefore cause it to heat up.

vetadmiral

dgrant3830

Your bad breaker explanation makes sense, However, wouldnt I be able to hear the motor working?

dgrant3830

Normally yes. However, what if a seat switch is stuck in one position and the seat can't travel any futher? To verify if this is a possibility, once its cooled off, put it back in and quickly move the seat to a neutral position. Shut down the car or shut off the accessory mode, but pay attention to the seat to see if it moves at all. Feel that circuit breaker for heat at different times. We're trying to find out when or what is causing it to overheat. Next, rememorize the seat position in any neutral position, then manually move the seat from that position, then touch the memory button once to make it go back to where you memorized it. Now on the C-5's, a famous failure item here is the seat bladders and the switch to run them getting stuck on, but yes, you would hear the little air compressor motor running.
Something in your seat is drawing too much current or running too long.

vetadmiral

The breaker I ordered came in and I installed it. I waited about five minutes to see if it would heat up, it didnt. So that seems to eliminate a short issue. Everythings works again! 8>D

However...

I set the seat positions, etc., for the #2 key and everything is fine.

I used the #1 key and the seat set at the last memory position. I was about to reset the seat memory and I felt the seat bumping forward, feeling like it was trying to go beyond the limit. I backed the seat up slight slightly and it stopped. My guess that may have been the problem. Before I set the seats for the #1 position, I thought I'd ask for any input on the forum. Otherwise, I'll reseat the seat and cross my fingers.

Any thoughts?

And thanks for everyone's help.

you can download a free .pdf owners manual for your '08 from the FAQ section above or GMPartsHouse.com.

Thanks for the tip, I’ll check that out. <PS, I have a 06 and it is awesome compared to my 89>

I’m looking for any antcedotal info that may be out there. I do have access to a hard copy of a 06 shop manual (on my living room coffee table right now). The section on the seats is pretty dense and appears to require anaylizers for which I don’t have access.

If someone has had this issue it could save me some research time. My guess is when I first got the 06; I may have stuck it in the full forward position while playing around with it like a kid with a new train set. Anyway, my guess (hope) is the seat wont cycle anymore now that it is out of the full forward position.

Has anybody dealt with this?

dgrant3830

If its inching forward on its own, I would be looking at the switch on the side of the seat.

vetadmiral

Thanks dgrant3830

I dont think its the switch because the seat doesnt cycle when the #2 key is used.

This leads me to believe it's either a limit switch in the motor or something in the memory. Or a combination of the memory and the limit switch challenging each other because the seat memory is set too far forward (which eventually wont be a too far forward issue because driver #1 is a full-figured guy <me>).

dgrant3830

Well, try and see if you can re-memorize the positions or disconnect the battery for about 30 seconds then re-do the memories again..window indexing and so on.

vetadmiral

dgrant3830

That's my next step; re-memorizing the positions for key #1. I had to quit for today and get caught up on e-mails. I'll do that in the morning after I make surer the breaker is still cool. I hope getting off the extreme position is the key.

I'd also like to see if anyone else has had to deal with this type of thing.

Thanks for your input.

vetadmiral

Today I took the breaker out, let it cool off. The seats worked again. I immediately moved the #1 key's seat memory off the extreme positions. That seemed to work. The Vette was driven for about a half hour or so and the seats are still responding.
I'm going on a drive tomorrow (Thursday) down to Tucson on some back roads (about a 100 mile drive on what's called the Tom Mix Highway). Hopefully any problems will surface on the trip.
I'm guessing a wire is binding in a extreme seat position causing a short. I think if I leave it alone I should be all right. I have the seats adjusted to where I want them so they wont be fiddled with anymore.
Any comments?

Vettdaddy

The screws that hold the motor to the seat frame were loose. Motor too hot to touch.
Thx CK
