I was installing my after market stereo today and when I pulled the stock one and plugged the aftermarket one in, nothign happened. Everything is hooked up correct so I plugged the factory one back in and nothing. I noticed that when I push the unlock button on the door the dash lights light up. The dome light doesn't come on, the door chime doesn't work and the keyless entry doesnt work. All the fuses are ok, what did I do? The car is equipped with a mach stereo and Im going to unhook the battery for the night. any suggestions? At first I thought it was the alarm so I ripped it out.
