My 2002 Trailblazer has a dead driver's door. - No window control, no mirror control, no door lock control. - When I lock/unlock with the remote keyless entry, it does not lock/unlock. Causes? - I was trying to hook my trailer up today and was checking for a blown fuse, I could have caused some problem? I didn't wire my trailer properly at first, could it have blown the fuse? My son was also playing in the car and he frequently locks/unclocks to car door even 15-20 times in rapid succession, could have blown the fuse then? Also, I just had this door window replaced, maybe the technician didn't hook it up fully and it came apart after a couple of days of driving? Solution? I've checked the Driver's door fuse and the Drivers door module. The rear windows go up and down, but they don't operate when I take out the module, so that is probably good. I've heard that other fuses can cause trailering problems becuase they lean on each other, I'll check all of fuses in the vehicle and see if I find one that's blown. OTHERWISE, I'll have to pull the door panel off, or call the window repair company and tell them they could have caused a problem.
