Strange Radio Noise
Help Guys , My 89 Chevy has a strange static type noise coming through the speakers at low volume to no volume . It comes through all speakers to . It goes away as it get to about half volume . Its all original , not tampered with in any way . its the am/fm cassettte with factory equalizer ( silverado ) . Could it be bad speakers , my truck is in really good condition with all interior items looking like it did in 89.
------------------ 1989 Chevy Silverado 4.3 v-6 Throttle body injected . Free flow Turbo exhaust system . four speed auto . 86 Rally wheels 15x8 RED with Gray interior . All original and in very good condition , like going back to 89 .

Sounds spooky to me. I'd check the antenna wire for a short. If none, RUN!!IT'S ALIVE!

Those radio "brains" are notorious for just eventually going bad. If the sound doesn't vary with engine rpms or anything else you can figure out, I'd try to find a friend who took their old radio out and stashed it on a shelf. Try it out and see if things are different. Those brains are easy to switch out.
