I'm interested to see what happens if you swap the seat memory module from the sports to the comfort seats.

Have you tried putting just the passenger Sport seat in, and the drivers comfort seat, to see if the issue is related to just the drivers seat (indicating tensioner, etc)?

:iagree:

Eliminate some of the variables.

Qsilver mentioned the comfort seat module vs. sport seat module. If they are different and I suspect they are (I have seen extra features on the comfort seats that the sports don't and vice versa) you might need to update the SA number and recode the GM module to work with the new seats. I might be wrong though...

You right about that..
New seats are just the seats ...
Slick .. You have to transfer all the electrical components from the old seats to the new one .. Like seats air bags sensors , belt tensioners , memories modules ,,
Been there done that ...

I was going to sell them, but right now, I have no friggen clue how this will all play out. I mean, it feels like I will have to buy a bunch of new parts, so eventually, when you see the X by my user name, that's when the seats go on sale.

No, I sort of did it in pair, because I wanted to make sure I can restore my car to NORMAL. I have confirmed that. Tonight I will pull just the driver seat.

So you are saying everything has to come out?

Thanks for jumping into this thread. I was hoping someone would have a definitive answer.

I am scratching my head here.

Any pointers on how to remove all the plastic trim around the memory modules?

Remove screw from back then pry off front clip and two bottom clips off. Swing out and up from bottom. Wiggle two top clips off (hidden). Below is a link to E46 seat fix video but describes how to remove seat module cover and the design of the cover is exactly the same as E53.

I recently purchased rear flares from TTGTR. Thanks TTGTR. Hope my project goes smooth... :cool:

Seeing that the TTGTR seats were in a wreck, is it possible the module has stored crash data?
