If you have a volume control that makes the volume go up when it's turned down, or vice versa, this may be of interest to you. I've already repaired this issue twice over the years in my 12-year old 1999 Pontiac Grand Prix. The fix for me was replacing the volume control in the stereo. This control is an "encoder", not a standard potentiometer. That is, it contains a pair of on/off switches, not a variable resistor strip. The part number for mine was printed on the side of it in hard-to-read lettering, and was 16209722. I'd suggest calling GM car radio repair shops to see if they'd sell you one (that's what I successfully did). As of this posting, the company at www.rivetech.com would sell that part to end users like me. I'd only suggest replacing it yourself if you have such soldering experience. Otherwise, take it apart and pay a TV repair shop or techie friend to solder it for you. Good luck!
