Driver window switch
Ive determined the drivers window switch needs replacing. Am I reading my SI correctly when it says it needs to be SPS programmed?
Any particular reason? (this is a model with out power mirros, etc.)
Most likely. It isn’t a switch, it’s a module. Heck I remember having to reprogram the seat switches because forward was back and back was forward!
The switch MIGHT be is a module. In most cases if the switch is not programmed the all the window cannot be rolled up and down . I have done a good number of window switch programming. Make sure to answer all the option question correctly, like the side mirrors are extended or other questions. Gm has been doing this for a while on there window switches
Yes, you read SI correct. The driver window switch must be programmed using SPS. Even GM SI doesn't give a reason or procedure. They state just refer to the SPS instructions.
Ok. Thanks gents Edit: Guess I need to clarify my resolution. I simply asked if the switch needed to be programmed. The first 3 gentlemen answered that question. Those answers seemed straight forward and were clear enough to me. (maybe not to others?) This trucks windows(like most,if not all GM trucks since the early 2000s) communicates on the low speed data line. (pin 9) Ive seen that…
I even had to program 2003 trailblazer door switch modules when I was at the dealership. So basically everything is a module with the basic info programmed into it but needs to be personalized to that specific vin as the part could be used in multiple vehicles.
There are 2 different types. One is a regular hard wired switch,it is not a module and will not communicate with the scan tool. This style does not need programming. The other is a module on the Low Speed GMLAN Bus and will comm with a scan tool. This one needs programming. You have to determine which you have.
Caleb- Are you talking about this generation of truck or do you mean GM in general? I haven't seen a direct wired window switch on a GM truck since the early 2000s. They all have been on the low speed data line for awhile, even the lowest base model trucks. (of course I haven't seen every GM truck type out there) However I dont remember ever having to program one, before this, hence my…
Yes most definitely this generation. Let me post some schematica later on.
Caleb- That's not necessary. I believe you. In this case, this truck does have a low speed bus line going to it and it IS a module. I just wanted input from those more familiar with this procedure.
if it not programmable version ( yes speaking of this year make model) it is usually the broken yellow wire in the door jamb. I have been called out to dozens of these due to dealer telling shop it needs programmed to find out not a programmable module and wiring issues. Keep us posted!
Brian- I have nothing more to add, my only question was the validity of the need to program the switch as stated in my SI. Most seem to think it does need to be, a few say maybe. The customer declined the repair so I cannot say with certainty, sorry.
I was looking at an '11 Traverse last week with window issues. There were a couple of options, with AXE (RPO) the switch was on the LIN bus as I recall but the vehicle that I was working on, without AXE, had no communication lines. Alldata stated programming was called for but I don't know how you program a switch with no data lines. This switch just sent a 12v signal to the various window…
type the VIN into here: tis2web.service.gm.com/tis2web and it will list every programmable module. Like Caleb said, sometimes you don't have to, on a more basic model truck.
Thank you Geoff , I was just typing that same reply and realized you had already done so.
Hi KDF! Love your new classes, but I sure miss the 5-minute videos. Those of us that know our theory out the wazoo, but live where the daily car count is TWO (or none) really benefit from all those "the wire was chafed here" type tips.
