    Headlight adjuster broken again

    Ended up going with plan b while trying to screw in a 6-32 threaded screw. I drilled a pilot hole with the intent to screw in the threaded screw. Once I did that, I realized how tight the screw was on the adjuster. Then it dawned on me to just cutoff the ball and have the screw adjust the...

    Headlight adjuster broken again

    Drove around this evening and the light is not even touching the road, it’s lighting up stop signs. I have no adjust control, it’s pop the white plastic over the adjuster ball or nothing. I’m going to try and screw in a finish deck screw through the back of the adjuster housing and through the...

    Headlight adjuster broken again

    Did mine today. The adjuster doesn’t work tho when I try to turn the Allen wrench. I just used a razor blade to open the top. Now I think my headlights are to high! What’s everyone’s ballpark light height from the floor to top of light on a wall?

    Headlight adjuster broken again

    Which direction did you go, drilling a 2-3” dia hole above the light or pulling stuff out from the adjuster side?

    Headlight adjuster broken again

    When you epoxy it back, are you able to adjust the headlight as if nothing ever happened or do you need to glue it to the desired height in one shot?

    2021 RST driver light went limp

    My light randomly went down. I popped my hood and started to turn the 6mm bolt housing and I could not go up. It was mismatching the passenger side by 10”. Now I can’t raise or lower the driver side any longer. Has this happened to anyone? From what I read, GM only has a 3/36 warranty on it and...

    “Service transmission Now, unable to shift soon” message on 2021 Tahoe

    Update… my battery was the issue. I swapped it out (scared af after reading on our bus bars & ECM stuff) and have no issues atm! (Can’t load pic, says file is to big). I was worried disconnecting the positive wire would cause ECM issues but… I was the test. There’s a small bar near the negative...

    “Service transmission Now, unable to shift soon” message on 2021 Tahoe

    I did take a picture and a video. This morning it happened again and I drove to the dealer and kept the engine running. They scanned it and said there’s a ton of codes popping up with a low battery voltage. They said start with replacing the battery and go from there. I also asked if I could...

    “Service transmission Now, unable to shift soon” message on 2021 Tahoe

    Well, I found this thread because I got the message today. After work I drove straight to the dealer and they did not see the message. They basically told me with no code, they can’t do anything. I left and about 3hrs later and roughly 6 drives later, I got it again but for only a moment. The...

    2022 Yukon AT4 wants BASS

    Nice setup. I have a 15” FI Audio in a 21 Tahoe. Did you add a High Output Alternator? When swapping battery, did you keep power connected to the vehicle at all times or disconnected pos/neg and swapped battery/lithium like nothing and have no issues reconnecting a new power supply (battery)?

    2021 5.3L Tahoe Alternator voltage?

    Has anyone swapped the alternator for a High Output Alt without having issues? I’d like to buy a stinger or mechman alt. I do plan to swap my battery soon, I believe the ctek 7002 charger can be plugged in and hooked up to the battery wiring to trick the Tahoe into thinking the battery is still...

    2021 5.3L Tahoe Alternator voltage?

    Those with a 2021 or newer, what’s your Alternator voltage w/engine on? From what I read, all the recent models share the same DC Delco brand, along with the AGM battery. I’m at 13.6 and want to see if others have a similar number. I’m starting to have electrical issues due to stock...

    What battery brand & installing?

    Sweet! My biggest concern is adding stuff and possibly opening a can of worms of codes due to new stuff not liking third party stuff. From what I gather, it’s not as easy as my old setup w/2nd battery, ** alt, big4, dual 0ga to amp with copper terminals all around. The new car electronics is...

    What battery brand & installing?

    I took my truck to AutoZone and they said my battery is good, just needs a charge. So I ordered a ctek 7002 to trickle charge. In the meantime, it gives me time to shop around for a battery. What do you mean by look at the battery number? Do you mean the group size?

    What battery brand & installing?

    Holy smokes, was quoted 832.77 for a battery replacement (DieHard agm battery included). Has anyone upgraded their battery yet (2021+ models)?

    What battery brand & installing?

    I have a 21 Tahoe and a 15” FI Audio sub. I’m about due for a new battery and curious what brand people are using. My go to XS Power doesn’t make a battery for us… yet. AGM battery is preferred. Also, I read it needs technical assistance when installing? Is this a sales pitch or is there some...

    How to turn ignition w/out engine on 21 RST?

    No oil in 2 spark plugs, one on each side. Went for a 20min drive and oil pressure seems normal. 28ish psi - 60psi from idle to 55mph. Can’t blame the oil change place to much as I should have checked my oil monthly at min. Lesson learned
