#389 of 609 1999 GMC Jimmy Electrical Problems
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

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

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.

I do know the hatch,door locks and mirrors are on the same circuit. If you have checked the accesory fuse(Ibelieve that is the one), It would be the relay. The
problems you have with those is that they draw a lot of power to operate. That's why there is a relay also and not just a fuse. If I remove the power accesory fuse,those same things do not work at all. I hope it is the fuse because I don't know exactly where the relay is. From 1995 to 2004 they made a lot of small changes. Your owners manual should help you find the relay if you find the fuse is good. I'm crossing my fingers and hoping it is the fuse. I hope this works for you and good luck.
