Oh, now I know why my lights get left on all the time. I was unaware till now that the aftermarket radio disables the door/headlight chime. My car came with aftermarket installed, I didn't know that happened. Why is it that the chimes are disabled? Can I make them work again?... Oh jeez i'm threadjacking again..
Well they don't get left on anymore.. but I had an issue with my DRL's flashing due to the high/low beam mod which I fixed now.. i'd turn my lights on to stop the flashing during the day and forget once in a while but I usually remebered. But the light and door chime would still be nice to have. I didn't instal any of my stereo except new speakers, haven't touched the cd player.. Just never knew that was why the courtsey module didnt work.
I am not using the Factory wiring in anyway shape or form on my 02, my cluster does the same thing from time to time.
Most 00+ J-Body cars I've installed radios in, with a Metra 70-2003 Harness, or a GMRC-01, sometimes some of the lights in the cluster stop working.
Damn J-Body issue.
If its that much of an issue you could remote mount the factory stereo on the factory harness somewhere else under the dash out of the way... and just use the speaker wires and tap into the power/acc/ground or whatever else you need to run your aftermarket stereo, and the factory unit should retain the dimmer controls correctly. In Theory that is
i got two 2001s and both have radios, one with the scosche harnest and one with my homemade trial and error method, neither have any problems. but i do remember to keep the chimes/buzzers that are "in my ears" annoying as hell you need the more expensive harnest, and if im right its was like $149.99 at best buy or some outragous price like that
