I know another ask the mechanic post. My parents have a 2006 GMC Envoy and lets just say the car has had it's fair share of problems after the 36,000 miles warranty was up. Now that i've fixed everything there is one problem i need some help with. The Service Airbag light is on, and apparently OnStar has read the code and said it comes back as Drivers Seat Memory Setting 2 Causing Air Bag Fault. I was wondering if anyone had any ideas as to what might cause this fault, or if it's a problem you've dealt with before and how to go about fixing it. The power seats/memory buttons work fine. I would bring it to the dealer but i'm pretty mechanically inclined and the dealership wants 125$ just to pull the code which OnStar has already done. So it seems like it'll be a 600-700$ fix.
