Spent like an hour trying to remove the boots to change my spark plugs. I gave up and ordering a boot puller.
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Got a link or pn for what you used? Got both bulbs changed out and only one lights. Probably because I banged that shit around trying to get it back in lol.

Everyone is doing it wrong taking apart the whole car to change out the bulbs
I found a simple solution that only requires 2 parts removed from the engine bay and child slave labor
as those little tiny hands can get into small space
Spill it! I couldn't even get the headlights out. Previous owner or dealer broke a headlight bracket trying before it seems.
Pass side, remove top headlight bolts and air cleaner box. Then there is a rubber cover behind the headlight held on by plastic clips. Trim tool those out and you can BARELY get in there. Really tough trying to get the headlight bulbs through without fumbling and touching the glass part of the bulb. But can be done, done it several times. And the turn signal and marker light bulbs as well. Hands get scraped up though.
Driver's side unbolt the top 2 headlight bolts, #2 battery tray and washer fluid reservoir mounting bolts. Hood cable gets in the way on that side too. Be careful not to break the WF reservoir prying it back. I believe there may also be a rubber flap on that side too. Putting back together be careful not to pinch the hood cable behind the WFR fastener.
If you’re referring to the DRL’s, pull the non-working bulb, and flip it 180 degrees. Some are polarity sensitive, so only work one way.
All you need is some harbor freight pliers like these, just grab the boot firmly and yank
I could have used these when I rounded off one of my diff cover bolts with a 12 point socket like a dumb ass. Luckily I invested in a nice 1/2" drive 6 point set that was able to bite it and break it loose. This would have been the next step if that failed.
Searching for metric 6 point socket sets it was difficult to find one that wasn't missing a handful of sizes in the ranks. I found this one that has all sizes in the order 12MM thru 24MM, very nice set if I do say so myself, nice locking socket holder holds them nice and secure too. (Not pictureed but every one of the socket holders have a spring/ball lock just like a ratchet.) One of my go to socket sets now working on the Tahoe.

Those pliers are like 20 years old btw, lol one of the few things that has lasted from there, my heat gun from there that had maybe 15 minutes on it died the other day the fan crept up to ludicrous speed and then imploded in a sparkly smokey death haha, had to get the wifes hair dryer out to finish shrinking some heat shrinkAnother tool for Santa's list.
I’ve had one of their heat guns for years, still going strong. I think some stuff is hit or miss.
I got a Dewalt heat gun it seems to hold up pretty well I had it for about 4 years now.
ya I have had mine for quit a while but it was barely used, I suspect that the last time I used it I kinda tossed it in my tool box a little too hard and it probably broke something inside.

Just got some 45 degree needle nose pliers from walmart. Gonna try again tomorrow
More than likely you just have the non working bulb in backwards... led bulbs have polarity and will only work installed one way... ask me how I know this...pop it out and flip it around and stick it back in... should work then...

The trick is to get down in the hole and try to pull the boot off by hooking the end of it. Pulling on it makes it act like a Chinese finger trap. Twist it first to "break the seal". I recall years ago having some that were really stuck. I used the Harbor Freight angled-tip long needle-nosed pliers and cut the tip down so it fit down in the hole.
Bought some cheap plug pullers and they sucked. Keep them around for some unknown reason. Bought the long bent nose needle nose pliers and they work great. Like the double link design.

Picture a rubber hose slipped over a barbed fitting. If you grabbed the hose where it's not on the barb and pulled, the hose stretches and tightens around the barb. Of course, if you grabbed the hose on the part that is slipped over the barb, you pinch it tighter on the barb. If you reached forward to the very end of the hose towards the base of the barb and "hooked" the hose to pull it off, the hose will tend to expand ("bubble out"), loosening it off the barb. This is pretty much the effect you want when unsticking and removing the boot off the spark plug.
