    Thanks, I go it...I was trying to get to the assembly after opening the bonnet. I found I had to remove the entire air filter assembly to get to the light assembly.

    Thanks, I got it. I found that by removing the air filter assembly(including the housing) you can get access to the light assembly.

    By removing the air filter assembly, including the lower half - which just pops out, I was able to remove the rubber lining which protects the light assembly from dust and dirt. I then just took the bulb out...

Well the owners manual for your machine says "owner's manual simply states that for all bulb replacement not shown to consult the dealer "

Best way I found was as follows:

1) Loosen lower, forward portion of driver side inner fender liner to gain access from behind by removing one 10mm screw from lower, forward area of fender liner (this is the one that threads into a nutplate on washer fluid res.) and one of the forward, outboard little screws (thinking it was 7mm) that sits just inside the fender. This will allow you to pull the liner back and gain access to the bulbs from low and behind.

From here I still was not quite able to access the bulbs from behind so I had to continue on by loosening the headlamp housing to gain additional clearance. Its possible that those with smaller hands *might* be able to get them. If not, continue as follows:

2) Remove the plastic upper radiator valance by pulling ~ eight plunger/grommet panel fasteners (I noticed one of mine was AWOL right off the bat).
3) Remove front grille by pulling four 10mm screws along top and then popping out six Tinnerman-style clips. I found it easiest to simply compress the clips from behind using channel locks and then gently pulling grille away from vehicle to unseat them one at a time.
4) Pull back the inner fender liner and look inside to locate one 10mm hex head screw securing lower headlamp housing. The screw head faces outboard and is about 3-4" forward of the inner liner.
5) Remove two 10mm screws common to the upper headlamp housing. Housing should now be "free".
6) Gently pull on the headlamp assembly while "wiggling" it side-to-side to disengage two aft-facing, alignment pins (located on the outboard side of the housing) and one small plastic tab (located on the inboard, lower portion of the housing).
7) At this point you should be able to wriggle the headlamp housing forward and inboard enough to gain access to the back side of the turn signal bulbs from behind. Be careful not to scratch the fender or chrome bumper "ear". Its a TIGHT fit.
8) Pull the inner fender liner back and then reach up through an opening in the sheet metal to get at the signal bulb connectors. Again, CCW to remove and CW to install the bulbs connectors into the housing.
9) Install is reverse. Be careful to properly realign the headlamp housing into the fender prior to buttoning up everything else.

The circuit board needs to be replaced. Which is the board that the bulbs sit in. If you remove the turn signal bulb. You will notice the bulb socket will be slightly burnt inside. I had the same problem with my 99 Denali and replaced the circuit board for $35.00. Now everything is fine.

Drivers side tail light lighting up at night when head lights are on but break light not working on that side. passenger side not lighting up when head lights are on but break light working on that side....

You probably already know this, however the GMC 2002 Yukon Denali uses the Wagner 3157 (or equivalent) dual element bulb. The running light uses one element whereas the brake & blinker share the other element that burns brighter.

Check to ensure the correct bulbs are being used. Then check all wire harness connections. Since the blinkers function, then it sounds like the connections are good.

It really sounds like there is a bulb issue, so check that first, then let us know the results.

How do I change the headlight bulb in my 2006 GMC Yukon Denali

There will be two steel arms about 1/8" round facing eatch other that are snapped into plastic retainers.If you turn the arm 90Deg (twords the front of headlight)and pull up on them the head light assemblie will come out giving you access to the bulbs.May have to squeeze and turn or just turn .Then you can disconect the wire harness.Just be sure when installing the new bulb not to touch it.I use a paper towl to handle the new bulb.If you get any oils from you hands on it this will cause a hot spot on the bulb and burn it out prematurely.Well hope this helped.
