Hey guys.

I got an 03 1500 4x4 with what seems to me to be an electrical issue. I press the AC button and sometimes the clutch engages, sometimes it doesn't.

Has anyone encountered this problem and if so what was the fix ? I was thinking of unplugging the harness off of the compressor and energizing it via a 12 volt jumper to see if it's the clutch coil or the head unit..

Whatcha think ?

  Feel free to expand on that. Considering .375" BORA spacers and extended lug nuts.

  I see that the existing powertrains are being carried over on the Yukon... I find that odd. I I initially was looking for a "now" buy but there are none within 250 miles with the equipment I want and the 2027's SOP is around the 2nd week of Sept. Couple of months and I move up a model year. The dumb things are priced about like an Escalade but no diesel or towing packages. I want the Yukon to have the trailer camera wiring. I have the GM trailer camera already installed on my trailer.

  I just got a 2026 with the 5.3. Learning about cylinder deactivation. Which one of these do I buy? https://www.rangetechnology.com/products/afm-dfm_disabler/parts/RA003B https://www.rangetechnology.com/products/dfm_module/parts/RA007
