Guage lights and heater lights do not work I cannot tell how fast im going at night and i caint tell if i have gas in the dark when I drive at night
Either the dash light dimmer is turned off or the dimmer control is defective.
SOURCE: have 2001 GMC Yukon XL, and noticed fuel guage
the fuel pump is inside the tank and i have seen trucks that the pump wiring harnes inside goes bad! when you turn the key on you should hear the pump running,if not i bet it is the wiring inside

you have a broken sending unit . it could probably be located inside the tank. must be replaced. can not be repaired.
have a sending unit ready and bring down the tank then replace it.

what's happening, is the level sensor in the fuel tank is getting worn out, and it thinks it's out of fuel when you actually still 1/2 to 1/4 of a tank left. The only way to rectify this is to put a new fuel pump in, as it is only available as an entire unit. If you can live with it, it'll probably last quite some time, but if not, you'll have to look at a pump assembly. Hope you get it situated soon! Feel free to reply back if you have other questions

There was not a recall, but there was a class action settlement where GM agreed to extend the warranty on certain vehicles for this problem. Check www.gmspeedometerrecall.com to see if you qualify.

CHECK ANTIFREEZE LEVEL IN RADIATOR MAKE SURE COOLANT LEVEL NOT TOO LOW.MOST OF THE TIME LOW COOLANT LEVEL WILL CAUSE POOR HEAT PROBLEMS.
