try a CHILTON BOOK with wiring diagrams
pull the trim plate off and unbolt or unscrew the bracket for the radio slide it out and unplug it
You need to push on the knob at the left...the same one used for volume. Et voila!
The Pontiac Montana does not come with a factory installed amp in the sound system. The wiring goes directly from the radio to the speakers.
There is no "reset" switch, that I know of. Everything on that car, programs either through the radio, or, with a Tech 2, through the OBD2.
Bcm is going bad
how do you remove the ignition switch on a 1987 firebird
Remove the covers to your 1997 radio speakers. Remove the radio speaker retaining screws. Remove the wiring harness from the back of the radio speakers. Reverse the process to install your new radio speakers.
Located behind the radio just to the upper right corner..grey relay box about an inch by inch cube.
You might try looking at http:\\caraudiohelp.co There is a world of info there. Good luck.
First thing to do is check the fuse. If the fuse is good then you will have to remove the radio and have it repaired or replace. You should be able to find a used radio at any salvage yard or you can install an aftermarket radio. That would be cheaper than having it repaired.
I have no clue but when I half plug in my speakers to my computer I get FM Radio!!! Its Crazy :)
