GM Repair Questions? Ask a Mechanic for Answers ASAP
hello and welcome to J/A my name is XXXXX XXXXX I will be assisting you today, please remember I am not their so be very detailed. how may I help you?
first thing I would need to know is do you have two keys? are they numbered 1 and 2? do you change keys? have you
Shawn..I have 2 sets of keys and 2 wireless controllers. One is labeled "1", the other is a GMC factory replacement from 3 years ago. No number, but hasn't given me any problems.
Shawn...I'm here if you're available
okay i am here
I'm in the car on a laptop, going through the fuse diagram if you find anything
can you try unlocking and locking the doors with one set of keys at a time and see if the seat moves with the remote key fob when unlocked
Yup, tried that. The pedals move from fob 1 and fob 2 like you'd expect from our user settings, but no seat movement or motor noise
okay unhook the battery both neg and positive sides take and hold the negitive to the positive wires (not the battery) just the wires hold the neg and positive wires together for 3 min then rehook them back to the battery this hard resets the computers and body modules
when after the three min and the wires are hooked back up you can try the seats and see where we are
Allright. Give me 10 minutes.
okay i will be here
hooking up battery now
No dice, I think.
Are we talking a full 3 minutes of continuous contact. I probably let up on the connection a couple of time?
as long as it was close to three min of continuous contact
I'll try it one more time while you're researching any other ideas. There are 3 sets of fuse panels. Can't find the center instrument panel fuse block, but can check the other 2 if you think you have an idea.
No dice on the 3 minute reset. Did find this GM Service Bulletin#03-08-50-003: Seat Heater and/or Memory Power Seat Inoperative (Replace Memory Seat Control Module) - (Jan 21, 2003)
i want to eliminate all other posibilites thou. i know about the module but its on the pricey side. trying to give the best possible service at best price outcome
do you have a test light? and does the heated seat led light up now?
I do have a test light, but the LEDs (both side) and seat adjust (driver side) are still inop.
ok can you get the seat control out of the seat?
Shawn...sorry to do this but I've hit my limit on time and have some kid issues to deal with. Can we try and knock this out later?
yes just send me a message when you get time
Shawn...The problem has been resolved. It was a bad connection to the ground under the seat...Thanks for your help...Don
