How hard is it to replace the ON/OFF/VOLUME knob on our cars. A friend I met at WENDYS with a MARK showed me his won't stay IN. Radio works fine. His antenna goes down when he gets out comes back up when he gets in and starts the car.

Just get a new radio

to change the on off switch you have to pull the stereo apart, i have done it a million times to change the whole switch, but they are practically free on ebay, just replace it.

Almost sounds like it's aftermarket time. When I pull mine out, I'm going to beat the :q:q:q:q out of it. It don't turn off at all and it's annoying the :q:q:q:q out of me. Already have the new stereo but haven't really had the time or good day to get it in.
