I had one but the radio was okay. Your volume buttons may be getting
stuck. The sudden jump to other stations indicate perhaps there is a
circuit board crack near the cpu or ground. Maybe there is some sort of
conductive debris inside due to the accident. Perhaps a simple screw
dancing around. Does the radio respond to shocks like a carefully well
placed thump? I remember the delco radios had this jumping stations
problem but due to the stupid intermittant eyelet contacts.


lb From: "lbbs"

lb We have a Winstar mini van, 4 years old. Most days when I listen
lb to radio the volume all of a sudden goes full volume (or sometimes
lb off). In the summer time I had a different problem. The radio
lb station would switch all of a sudden to a different channel. Or it
lb would switch from cd to radio, all on it's own. Could a short in the
lb wiring that going to the speakers, cause such a problem? This van
lb has been in a medium front end collision (damage in the rad and bumper
lb area), and has been fixed. As far as I know there is no wiring
lb relating to the radio that goes anywhere neat the front of the van.
lb I would like to find the least expensive way to fix it. If it is a
lb short, I could take out the radio unit and see if I can find a short.
lb Any ideas? Thanks.

.... Which sparks some mnemonic circuitry.
