I have an intermittent problem with my GMC 2001 Jimmy .The dash board and all lights in the car go out and come back on in about a minute or two day and night.Is there some kind of switch or relay
Also the brake and ABS lights come on sometimes,and I know the parking brake is off.
What Is the fix for this problem?
Hi Poppalair1, I researched your issues in the Owner's Manual of your vehicle. Please review pg. 4-8, Anti-Lock Brakes (ABS) when there is a problem with the anti-lock brake system, this warning light will stay on. See “Anti-Lock Brake System Warning Light” the Index. I did not find any information on the intermittent dashboard lights problem. Because I am not a technician, I recommend you visit your dealer to get a proper diagnosis. Good luck!

If you havent resolved the problem as of yet ... GM is famous for poor grounding on their electronics. Most likley its just a bad ground connection to your dash. Try running a new ground wire from a good chassis point to a solid metal part behind the dash
I have the same problem. I find that if I move the dash light dimmer switch the lights come back on. The problem is the switch. I am looking for instruction on changing the switch.
On the serious side truck is 16years old.computer may be on the way out.check diagram for all lights/warning lights
