#389 of 472 1999 GMC Jimmy Electrical Problems by tberg765 Jun 21, 2009 (7:24 pm)
We just bought a 1999 GMC Jimmy and are having electrical problems. We will be driving down the road and the the ABS, Security, Seatbelt lights come on, and also the Gas guage goes to E and the Temp guage goes to 0. Also, the air conditioning with start blowing hot air for a few seconds and go back to cold. Even if the air is off, it will start blowing heat full power for no reason. We just replaced the BCM and that did not fix it. I did notice it is worse when on a bumpy road, or stopping and going a lot. Any help would be appreciated t_berg18yahoo.com Replies to this message: tidester (Jun 22, 2009 9:38 am) cardoc50 (Jun 22, 2009 1:01 pm) jlflemmons (Jun 22, 2009 2:33 pm)

Doing so would deprive others of valuable information and tends to defeat the purpose of a Forum. Our members prefer to share information openly.   tidester, host SUVs and Smart Shopper

Replying to: tberg765 (Jun 21, 2009 7:24 pm) The electrical problems you describe on your Jimmy sound like a(or more) wires shorting to ground. I think you should take it to a reputable repair shop.Preferrably a Chevrolet or GMC dealer. Ask around and find a good one. The part about it getting worse when you hit bumps almost assures me that something is shorting out.Did you buy it from a dealer or independant person? Can you contact the person that had it before you and ask if they had problems with it? These Blazers and Jimmys have had so much go wrong in the electrical system it's almost impossible to determine the source. Sorry I can't help more but,you need to take it to a good shop because I'm sure they have ran across the same thing many times.By the way,do you want to buy a 1997 Jimmy? LOL

Replying to: tberg765 (Jun 21, 2009 7:24 pm) Check the grounding from the negative side of the battery to the engine, and also to the frame/body.   A poor ground can also yield may bizarre symptons.
