All lights go blank after gmc envoy 2002 warms up. why?


There may be a bad wire somewhere. I would check first the the thermostat and its wiring for exposed conductor or bad insulation or wires in contact with metal or other wires. The thermostat is located at one of the radiator hoses. It looks like a plug from the outside and has wires connected to it.

2002 GMC Envoy, i put the key in ignition and vehicle will not start sometimes and other times is starts fine. we have checked the starter, battery and battery connections, all fine. Changed the starter...


Ignition switch and neutral safety switch. Next time it happens wiggle thekeys in the ignition switch and try to restart.If it starts its probably the ignition switch. Then locate neutral safety switch on brake pedal and put meter on B+ wire from switch to starter relay and see if you get B+ on the would -be- crank. Next locate B+ wire from starter relay to starter hook a meter to it and see if you get B+ on the would -be crank.
Where ever B+ is missing is your problem.

Need fuse box diagram 2002 gmc envoy


If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

Replace starter on 2002 GMC Envoy SLT


check to see if the starter itself is getting a signal to crank. youll need to use a test light and have someone else try to start the vehicle, while you probe the wire to the starter to see if it is getting power. if not, check the starter fuse to make sure its not blown, as well as the starter relay to make sure that is good too (very common on gm's for bad relays) if the fuse and relay are good, but your not getting signal, it is an ignition switch problem.
