On my 94 LC, the sound will randomly cut out on my stereo. It has an aftermarket radio and has since I got it. I figured it was the radio going bad (it was an older style Kenwood with no AUX), so I bought a new radio w/ AUX hookup and installed it (along with a new harness). Still doing the same thing. Radio stays powered up but loses all sound. If I shut the car off and turn switch back on, sound will come out for approx. 5 seconds then go out again. It seems to do this a lot more when it is warmer outside. When it was cold, I never had an issue. As the weather has been getting warmer, it did it more and more and now it will barely work at all, if any. Any ideas? Obviously, stereo is good, checked wiring in dash at radio and all seemed tight with good connections.
