So, I bought an "older" car to replace my grandam that I blew the motor in. The factory car stereo does not work at all unless you have the drivers side door open approximately 2 and a half inches. I've read some stuff on this where the wiring might be linked with the dome light, but my dome light has never worked since I got the car even replacing the fuses and bulbs. It is a 94 plymouth acclaim, any ideas why these don't work?
