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.

SOURCE: '04 GMC Yukon Denali Check Engine Light

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

SOURCE: location of fuse box/panel for 2004 yukon denali xl

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.

SOURCE: How do you change the transmission fluid in a 2004

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!

2007 Yukon Xl Denali can the headlight switch/dimmer cause only the tail lights to not work. Dash lights, signals, brake lights when pressed work. Both sides went out. No blown fuse or broken wires.


If front park lights are working highly unlikely headlight switch is the issue. Is the vehicle equipped with a trailer towing package and wiring to the rear? I would start there. This vehicle may also have a taillight module located under the vehicle on the passenger rear attached in the wheel well area that goes bad

2002 Yukon denali headlights not work....all otherlights and signals work fine, it is not the headlight switch or the switch on the column any ideas?????


Check the solenoid switch on the electrical panel under the hood. Just switch the solenoid for the lights with one of the others just to test it. This is a cheap thing to replace.

The parking lights on our 2001 GMC Yukon XL stay on after turning the vehicle off. This drains the battery down to prevent starting again. What is wrong?


Hi, there is a park relay in middle of the interior relay box under the dash to the left of the steering column. This is shown on page 6-61 of your owner's manual (http://www.extendedgmwarranty.com/owners-manual/gmc/2001-GMC-Yukon-Denali.pdf)
With the battery connected, pull out the relay and push it back in. If it clicks when you do this, the headlight switch is bad. If it doesn't click, the relay is bad. Try swapping the relay with another similar relay, such as the horn or A/C relay. If that solves the problem you need a relay. If not, you need a switch. Please let me know if you have any questions, and thanks for using FixYa.
