Stereo & Electronics - Factory Cassette Player

My Radio in my 94 is factory and lately it has been getting real warm when lights are on. All the Preset buttons are very warm. What is with this? My 01 CD player doesnt do this.. I disconnected it because I dont want to ruin my factory player for my car..

couldnt you just buy an aftermarket headunit and wiring kit if your worried about keeping it stock just put the old one back in with the orginal wiring when you go to sell it. and then your factory one will be safe in your closet or something

Yes most likely I will do that, but its just strange. Even when I put my finger throw the tape dust flap I just feel the warm air. And the heater is not even on..

yea id just let it sit in my house if u want to keep it so its original later. my take it to a stereo place and see if they can take a look at it.
