Question about 2004 GMC Envoy

1 Answer

Stereo speakers only work when outside temp is 75 or greater. No continuity to speaker wires. According to schematic diagram I suspect connector c304 is not connected properly but I can't find it. Where is the connector and although I don't think there is an amplifier, if there is where is it located? 2004 4 wheel drive 6 cylinder GMC Envoy XUV

There have been problems with speakers doing this over the years. and there are 2 points number one the speakers in the doors are getting damp and the connector on the speaker/s has become unworkable. 2 the amp on the radio itself has a problem ( amp can become temperature related i.e there is the main amp chip sits on the heatsink some will become used to certain temps and turn off if not at this temp or goes over it. there is a working temp on some of these chips between -3c to 75c any higher or lower it will not work this setting in the chip can go wrong) . what you need to do to determine what is what you need to take the door panel off and test the speaker in that door.. if it is the external amp there is 2 areas it can one is under the rear seat the other is the the boot side panels this all depends on the amp fitted. if under the back seat there is sometimes a chance of damage from rear passengers jumping up and down on the seat... hope this helps.

SOURCE: 2004 GMC Envoy XUV mid-gate window won't roll up

be sure the gate is fully closed or it will not roll up if it is firmly in place and still does not go up you will have to remove the cover and see if the actuator plastic has broken off from the switch, it also could be a bent rod and or the switch is bad. Check fuses as well just to be sure before going to all the other work to pull cover off. Hope this is helpful and thanks for using Fix-ya.
