Honestly, not that I’m aware of. My thinking is after 8 yrs and 135k miles, but new to me, it might benefit from it. Admittedly, I obsess over preventative maintenance to a fault.

Hope you don’t flush some junk into the injectors and plug them up. Might do more harm than good. If it ain’t broke....

Has anyone installed LED High/Low beams in a YUKON DENALI and been happy?

Which brand etc..... Soryy but SEARCH is FUBAR..
I plan on using the sealight ones for my Tahoe. Low and high. 80 bucks For the pair. I’ve spent more on shit I never used so why not. Otherwise I’ll be switching to Japanese hid kit from the auto parts store down the block. Anything is better than halogen.

Finally did the foglight mod with the diode @Rocket Man sent me.

I couldn't have picked a hotter day to do it, it's about 95* here, and when I first pulled into the garage after getting home from work about 1pm, it was 105* in the garage.... Lol

After turning on the gable and ceiling fan and opening the windows it got down to 95* in the garage.

@Doubeleive The foglights DO come on with the DRL I found out after pulling it out of the garage to test in the sunlight. Not sure if I really like them basically being on all the time, even in the daytime.

The diode did get warm, especially when the high beams were on. I took some temps with my IR temp gun. With vehicle off, diode temp was 100-105*. With vehicle running and low beams/foglights on, diode temp went up to about 120*. With highbeams/foglights on, diode temp got up to 140*.

I only had the highbeams on for a few minutes. Not sure if the temp would continue to rise if I left them on longer.

I ran my jumper off from the parklight (15a fuse)

Good day gents!

Finally got the front strut/mounts and rear shocks in, new rear tires since I smoked them off.

Have a FAST LSXRT 102 intake on the way (already have a Snake Eater Performance 102 TB in the garage. I also have some Hellwig adjustable rear endlink arriving today; since the OEM ones are no good with the 4" drop on the rear.

Work has been uber demanding and we went to the lake for a week for my burfday/fathers day.

Question for the masses..... Last week the AC in the PPV was fine, but over the last several days the AC is only blowing at 64-78* what have yall had to do for AC repairs? According to GM the AC temp at the vents should be near 50*

At this point I have verified that the compressor is operational, i also went through the reset procedure for the blend doors/controls and there is R34 making it up to the dry and evap.......but not cold enough.

Thank you for bringing that up! I actually read about that in an old post of yours, and got under and checked them myself. While they were not as tight as I'd like them to be, they weren't loose enough to cause a clunk.
Mine did this too

I took a leftover add-a-circuit fuse tape I had laying around in the garage and put it on the right parking light fuse (position #27) because it had no fuses above it to block.

I had a 5a fuse in there and it ran the foglight relay whenever the parking lights are on. I tried a 2a fuse but it popped. I currently have a 3a fuse in there and it seems to run fine.

The diode probably doesn't need to be in this circuit, but I left it in there. The temp of the diode when lights are on is about 140-145*

I haven't tried it outside the garage in the daylight yet, but I'm sure the fogs won't come on with the DRLs, which on the yukon are the low beam headlights.

Thanks for taking the time to investigate. So the coil side of the relay pulls over 2A? Wow, didn't expect that. Good tip on the add-a-fuse thingy, too. That's likely to come in handy someday.

Is the diode needed doing it this way?

I don't think it is, as the fogs will only be on when parking lights are on. When you turn the dial over to turn off all lights, then press the foglight button, bith the fogs and parking lights come on, which they were always like that.

I still have to see if they come on in the daylight. I know the parking light fuse doesn't have power when the truck is off and the parking lights are off, and only gets power when parking lights are manually turned on or the headlight switch is on auto and it's dark and all lights come on (currently parked in garage).

So are you saying when the truck is off and it’s set to auto the fog lights are powered?

My last sentence is a bit confusing. I forgot to say when the key is on and the switch is on auto all lights come on while it's parked in my garage

That’s ok. Works for me. Fog will always be on at night then this way. I leave lights in auto.

I just ran to the hardware store and fogs stayed off in daylight with the DRLs on. I could push the foglight button and they along with the parking lights came on, and turn off when I push the button again.

So basically, anytime the parking lights are on, so are the fogs. It doesn't matter if low or high beams are on, the fogs stay on and don't come on during the day while in auto and DRLs are on, unless you turn them on by the fog light button.

You need to do a write-up in the tech section with your method.

Ok. Adding some add a circuits to my amazon order.
Make sure to get the ones for Mini ATC fuses, NOT Mini ATM.

Also, to install it correctly, the fuse you pulled from the fuse box goes into the bottom connector and the newly added circuit fuse (3a in this case) goes in the top connector
