Windows only go down from drivers controls
The windows on my 2003 se will only go down from the driver controls, but will go up from drivers controls or each individual control.
I tried replacing the drivers controls with a new unit from GM but that had no effect. I don't have the driver info center, just the standard, so I don't think that it could be that something is programmed wrong in the drivers info.
I read something about a rear integration module that sounds like it could be the problem. Where is this module and any way to check it without replacement?
