Hi everyone I am new to this thread and joined because well I saw this site on Google and thought I would fit in quite well here. I own a 2001 Chevy Monte Carlo SS 3800II Naturally Aspirated. She's got 200k miles on the odometer but 80k on the new motor. Ever since I've had the car I noticed the DIC doesn't always work. However just recently I've realized that when it doesn't neither does the air, cruise control, auto dimming mirror, and rear defroster. I've tried check the fuse and it was fine. However it always comes on, not always at the same time though. Sometimes 5min -1 1/2hrs. Just would like to know what I can do to fix this and hopefully its not an expensive fix considering I just spent $1150.00 on a new motor.
