Hi all,

The stereo in my 92 Chev Silverado is acting up. The problem is that
the audio to my speakers is cutting out and replaced with a loud
repeating popping sound in the speakers. The volume of the popping is
unrelated to the volume setting. The fuses are all fine.

When I listen closely to the dash, it sounds like there is a relay
clicking on an off in sync with the popping.

When it is cool out, like first thing in the morning,  the problem goes
away. After a day in the hot sun, the problem is back.

Any ideas???

Thanks very much

Mark
