Question about GMC Yukon Denali
I agree to check the fuses. These trucks have 2 fuse boxes if I remember correctly, one under the hood and one inside the door jam. I could be wrong but I can't remember exactly. If the fuses and relays are good it could either be the main switch on the dash bad or either the dimmer switch is bad. Had to replace the dimmer switch on the steering column in my 2001 Yukon about a year ago bc my low beams quit working.

They have fuses these days, check them.
Also check to make sure the fuses get power with them turned on or the switch could be bad................... but I have seen two bulbs go gad at the same time.

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.
The ohter is under the dash and above the pedals, this one is much tougher to access.
Your Owner's Manual should tell you where the fuses are that you need to access.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

At the bottom of your transmission there is a large square/rectangular pan (depends which trans you have). Have a large drain pan to catch 5 to 9 liters/quarts of transmission fluid. Undo all of the retainer bolts and carefully lower the pan (this can get messy for the unexperienced) .
In some cases the rear transmission mount may need to be undone and the rear of the trans lifted to allow clearance for the pan to be slid past the crossmember.
Replace the trans filter too!

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem
