Reset service light 2001 yukon


the answers above do not work. batter cable off does not work. that turn on 5 pedal thing is BS. also some a holes online are saying undo the fuse cover under the steering wheel and and unplug the ECU - well the fuse panel is not under the wheel, it's on the drv side of the dash. AND even when you pull that there is nothing called a ecu. funny hu. there is not a ECU fuse in the under hood fuse box either. service engine soon light is STILL ON. It was flicked on from the air breather intake being loose. that has been fixed. gas caps on tight. engine oils been changed.

Lights or fuse for my speed odemeter guage and heater/air conditioning system


These lights for the dash are controlled by a rheostat instrument control dimmer switch next to the main light switch for the headlights, it is either turned off (have seen this dozens of times) or it is defective. Below is a picture of the switch assembly I speak of. The thumb wheel next to the knob is the dimmer control.

Will not go into four wheel drive when I push the button no light comes on. 2000 gmc yukon denali


I would venture the guess that your button is broken. The easy fix it to remove it and jimmy rig something manual to activate the function. Then everything will work fine. Additionally, be careful not to let your contraption rub against the actuator under the dash in that area because it could spark while you drive.

I have a 2001 GMC Yukon that will not shift into four wheel drive. I can hear the click, when I push the button and the light blinks but it will not remain solid and I dont think I should drive it without...


it sounds to me like the motor that switches the transfer case into 4 wheel drive DO NOT try to put it in 4 wheel. There should be no problem driving it as it is but if you continue to try it may get stuck in between and cause major problems

4x4 will not engage in 96 gmc yukon


I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,

This means there is a fault in the four wheel drive system, the light reset's each time the key is turned off, then it tests itself after the engine is started, if the fault occurs again the light will come back on.
