I just fixed the bad digital dash problem with my 93 Jimmy. Turns out that this is a common problem. There is a mother board behind the digital dash. If you enter "digital dash 93 Jimmy" into your computer search engine, several providers will pop up. One of them (and he is on ebay) charges $55 for a rebuilt mother board that you get in the mail in about 5 days. If you buy the motherboard only, your odomiter is unchanged. If you buy the "rebuilt digital dash for $125, you will not be able to retain your correct odomiter reading. The mother board kit Includes instructions to R&R the board, pretty strait forward. If you are half handy, you can do it yourself in about 2-3 hours, just follow the instructions. The only headache was the heater control. FOLLOW THE INSTRUCTIONS carefully and the second time you reinstall the heater control, it will make sence. All works great now!

It means that you probably had your battery drained recently and the radio is now LOCked out. There is a (complicated) procedure for unlocking it and I stumbled upon it at this site: Automotive Helper - Radio Locked Out
 
Alternatively, any GM dealer should be able to fix it for you.

I HAVE REPLACE THE FUEL SENDING UNIT TWICE. BOTH TIMES THIER WER INDICATIONS THAT IT WASNT GETTING FUEL. PARKED THE CAR AT NIGHT WENT OUT THE NEXT MORNING AND WOULD NOT START. I HEAR THE FSU SPINNING UP AND FUEL CAN BE RELEASED FROM THE PRESSURE CHECK VALVE. DO THINK IT COULD BE THE FSU AGAIN? OR SOMETHING MORE SERIOUS

I have recently purchase a 1999 GMC Jimmy. the remote was not working when I got the car and the dealer said it needed a change of battery.changed the battery and now everynight without fail the alarm kept on going off at ungodly hour.I have since went to the GMC Dealer and they gave me a brand new remote and have configured it. However, the alarm still goes off. any advise ?? the alarm is driving me crazy.

Check the door switches and make sure they are OK, and is the battery voltage OK.

aftermarket alarm???? by rsolo956
Feb 09, 2008 (4:34 pm)

I recently bought an 86 Jimmy in great shape from an auction. After taking it home I noticed an LED lit up, the doors locked and I could not crank the vehicle. I did find a GM goodwrench box (which looks to be an aftermarket alarm or something) next to the fuse box and a off and on switch next to it which I have already tried to disengage to no avail. I have to disconnect the battery to reset everything and it will crank. Now does anyone know if I can get a remote from GM, or does anyone know how to disengage it?? Help is greatly appreciated.

Break Light on drivers side wont light up by buzz66

I recently bought a 1999 GMC Jimmy SLE and noticed the break light on the drivers side wont light up. The other break lights as well as all other lights work as they should...just that break light. It's not the fuse and it's not the bulb. Any ideas what I can check next? Thank you.
