I have a 03 chev 2500HD ext cab long bed,duramax/allison,stock. My problem statrted with the drivers seat not work at all,so they replaced the rails and that didnt do it,replaced the motor and that didnt do it so ended up replacing the memorey thing and everything seemed to be ok. Then my dash gauges wouldnt work some times,particularly after sitting for 2 or 3 days in the garage in Calif,so they re calibrated them. I have the auto set in the off position. Ive had acouple cases were 1)I just turn off the ignition key and the drives seat retracted,2) key in ignition motor running and I roll both windows up at the same time and the seat retracted 3)Turned off ignition radio still on removed key and the radio changed stations and the seat retracted Weird or what.
