Question about 2007 GMC Yukon Denali
My front right hand turn signal bulb is burned out on my 2007 GMC Yukon Denali. I am good with automotive repairs, but cannot locate a way to access and replace the bulb.
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.
