< I've had a 93 Deville for some time now, and it seems the two times I've used the cigarette lighter, it's killed or messed up the systems for my power locks and made the stereo crap out. The stereo crapped out right after I pushed in the lighter, and now, this is pissing me off, as I can't stand not having any music. Non bose unit. Please someone help me.

 

Apparently the radiois wired into the cig/power lock circuit. When the cig lighter is used, that load is too much on the radio. I'dfind a new power supply for the lighter or the radio.
