New to owning a Yukon Denali

[kwyellowrr]

I have owned a 2011 Yukon Denali for about a month now. Very happy so far. Driving a full size SUV is a huge upgrade for me . This was a previous car service rig very well maintained and taken care of by the owner. I just lost the high and low beams driving home tonight! Luckily the clear fog lamps are bright enough and got me home. I checked all the fuses(all good) and replaced the headlamp relay , still no head lights ! Can anybody offer some insite?

I have an appointment at the garage that has serviced it since new , but i thought is I could fix it myself. I could save a few dollars.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

I cannot personally assist you with your issue, but other members of this Forum much more knowledgeable than me in this area will chime in. I would say, however, if you've lost both high and low beams to both sides, then the source of the issue may be in your light switch on the dashboard.

although rare, it's possible both bulbs burned out, the yukon's use a dual bulb, meaning a single bulb is both high & low beam
could maybe... be the switch but if the running lights come on then maybe less likely but still possible.
you have to do a song & dance to change these bulbs either by pulling the bumper cover or there is a shortcut to do it by removing a few bolts to get the headlight out

that being said you "should" be able to reach the back of one side by removing the wind flap and reaching in, this will allow you to pull the bulb abd check it or try a new bulb
the yukons are wired weird so checking the harness for power can be tricky because again it is a dual bulb and splits for the blinker and running light.

Wonder if these bulbs have a common ground ? Could be problem if so....

Welcome from SoCal. You’ll need to be familiar with how to pull the headlamp assembly. There’s also a smaller running lamp in the side of the assembly that’s out too.

Don’t be like the guy in the video and touch the bulb with your fingers. The oil in your skin gets on the glass, cooks on the glass and quickly burns out the bulb. Check the fuses before the bulbs because it’s easier. I always used PIAA / Valeo bulbs without the blue tint. They about 15% brighter but there’s no impact on the service life.

The below video is the best headlight removal / bulb replacement one on YouTube IMO.

I have since had to change my headlight bulbs twice, 1 side went out on me after like ~15k miles from me replacing (annoying). Note the grill has to just sort of 'pop' forward, it will not be fully removed. And you access the back side of the headlights through the wheel well; wheel can remain on to remove the 3-4 bolts/clips of the wheel well liner. It looks like an obnoxious repair but it's actually straightforward. Just watch when you are sliding the headlight assembly in and out that you don't scratch the fender paint; taping it up may be best.

Above post is correct. Grab your kids boogie board or cardboard to sit on the first time.

Budget for the Alpharex plug n play headlamps. Going to HID or LED is like getting your 1st pair of prescription sunglasses. No more squint, eyes wide open and driving confidence at night goes up 2-3x because you can see that much more.

My hefty lighting investment - worth it - Alpharex and Diode Dynamics

Did a bunch of research on headlight and foglight options, and settled on the "buy once, cry once" philosophy. I cried. A lot. o_O Settled on the Alpharex NOVA series LED projector headlights. Click here And went with the Diode Dynamics SS3 Max LED fog lights. Click here I wanted quality...

This is a great video for doing this task. He doesn't waste time with unneeded descriptions that mean absolutely nothing. Straight forward and too the point and great pics of what needs to be done.
