My 2004 Envoy XUV has been suffering for a while from a flaky instrument panel computer that identifies an "Unknown driver" and most of the dash computer output is off. This has always been confined to just the instrument panel and has not affected any other functionality so was just an annoyance.
This morning everything was working normally until I made a stop on the way to work. When I restarted the car, I noticed the following were not working properly:
Dome Lights were on but when I checked, all the doors were closed. The dome light did respond to the switch on the dash and could be turned off with the switch but otherwise they are on when the car is on.
A/C blower was working but was not blowing cold air. Fan control works fine.
Passenger side mirror would not respond to remote control on driver door but the driver's side mirror works normally.
Radio does not come on. This is a NAV/display unit, when you press the button, the display lights up for a few seconds and shows the time but then goes dark without actually turning on the radio. It obviously has power to at least a portion of the unit.
The driver and front passenger door power window switches are inoperative. Didn't try the back doors. Midgate window does work from switch on the overhead console. Seat heater and all buttons on the driver & front passenger door are dead.
Power locks on the front doors do not work nor does Key FOB to lock/unlock the doors. I had to lock the car manually and open it with the key.
There may be other things but that's the extent of what I observed. Other than these, the things I tried seem to be working properly, lights & turn signals are ok, engine runs and shifts fine.
Has anyone seen a similar issue? Or does anyone know what might have such a widespread impact? In looking at the fuse map in the manual, nothing stands out.
