QuestionA couple of months ago, I went to circuit city and had a radio installed in a 2002 buick lesabre and they didn't have the $100 harness, so they sent me to another shop that had a harness that would fit, but it wasn't the $100 one, it was $15 dollars. they told me that i wouldn't have doors chimes and that was about it, but now when i turn my radio past the volume of 40, my brake and abs light comes on, and sometimes my car won't start. I put on new brakes, bought a new battery, and checked my alternator and everything checks out fine. What do you think is the problem and do you think i need to get the $100 harness?
Answeryou,you been driving a month like that, you are lucky i seen car go to the dealer in tow truck because of what they did.
this was a very bad idea you can damage the vehicle computer
install the factory radio asap or get the harness repairs for saving that money can cost up to $700.00
try not to drive the vehicle anymore
here is a link to the interface that the vehicle BCM needs to see
