    Must wait before starting

    Solution to intermittent start- it got worse after I originally posted and sometimes I couldn’t start the car for 2-3 days. It ended up being two issues, which is why it was hard to nail down/diagnose. The primary no start when I would hear clicking sounds that sounded like a dead battery was...

    Must wait before starting

    2011 Yukon XL 5.3 flex fuel. I had electrical gremlins/issues last spring that turned out to be a bad negative ground. I replaced the negative and positive cables with new AC Delco. Following recommendations I received on this forum, I also replaced the block to body ground strap (PITA to get...

    07 Tahoe does A/C compressor cycle on and off?

    We bought this truck in 2019 and in the two 25-30 min test drives we took in 80-85 degree weather the A/C worked just fine. Gave no indications of an issue A month later we took it on our first road trip where we drove it longer than about 25-30 minutes continuously. Leaving around 4 am the...

    A/C sometimes not cold when idling

    I ended up borrowing a sniffer and spent a good 3.5 hours 'sniffing' the whole system from rear to the front looking for a leak. Found nothing initially. Then I turned the front system off (rear on) and picked up a very faint leak coming from center dash vents. Dang it..... Very Very small...

    07 Tahoe does A/C compressor cycle on and off?

    I had a similar situation in my ‘11. The AC wouldn’t cycle off, evaps would freeze over. Nothing would blow through vents even though fan motor was blasting full strength. I tried resetting vent flaps/recalibrated actuators/etc. Turning off the compressor briefly would solve the problem for a...

    A/C sometimes not cold when idling

    2011 Yukon XL. A/C works great while traveling down highway, very cold. However, when sitting in parking lot or in line at drive through air vent temp climbs from a frosty 38-42 to 70-75. Not fun in traffic jams at 95 degrees, but also not a failure. Had the charge tested and system leak tested...
