hey i have a 99 3.8 liter camaro and i just put in a new stereo and there was an aftermarket stereo in there before but this time when i put it in when i try to roll down my windows my stereo just shuts down like i turned off the car and the windows dont work either and they dont work unless i dont start the car for a couple of weeks and ideas??

 

Check all the wires. and the body mount ground wires....
