I bought the 99 DeVille about a year ago and the guy who previously owned it cut the radio harness to install a new radio...which led to a huge nightmare. Anyways, I got the factory radio back in, and everything works except the antenna, it wont raise up when the ignition is on. What are the wire colors I need to look at on the harness to make sure they are hooked up correctly. Secondly, only my right side speakers work, left side front and rear do not. I checked the balance on the radio and it was in the middle. Im assuming the factory amp is a 4channel. I dont see how the two speakers could have blown, or the 2 channels blow. Im assuming the problem is in the wiring behind the radio. Any help would be appreciated.
