    A/C problems

    Update: I read on the net about testing the compressor using a jumper wire at the relay panel under the hood on the driver's side. I didn't see where I could touch the wires, but saw that the fog lights use the same relay. I pulled the fog light and stuck it in the A/C, and the compressor...

    A/C problems

    Has anyone had their compressor quit yet? Noticed yesterday the air wasn't blowing cold and took a look under the hood and the compressor wasn't running. 2007 Denali XL with 166,000. Tried the old paperclip jumper at the dryer. Sounded like the idle changed, but the compressor didn't kick...

    Process to replace Autoride compressor

    It's a pretty easy plug and play. I replaced mine on my '07 Denali. It's been a year and a half, but I'm pretty sure it was easy. Just crawl under the back corner, unbolt, unhook electrical harness and unhook air hoses. I cant remember the name for the air fittings. I think you push in on...

    Can you siphon gas out of a 2007 Yukon Denali XL?

    There is a check ball. You can disconnect the filler hose from the tank and get a hose in that way. I had to drop my tank to replace the fuel pump. I got about 15 gallons out using a hand pump.

    08 Denali XL gremlins

    I used an OEM. My brother works parts at a Chevy dealer, so I paid $300. Also, I remebered over the weekend that the MPG and fuel used data started being off. I drove Denver to Chicago and back and dash said I got 20 mpg. I wish!

    08 Denali XL gremlins

    I have an '07 Denali XL and it was doing the same thing. It would die at a stoplight after driving for a long time. Sometimes it wouldn't restart for 45 minutes. It seemed to be worse in hot weather. It felt like it was vapor locked. I know it couldn't be, but that's how it acted. I...

    '07 Denali hot stall?

    Late Update: End of August it stalled again at a light. This time started back up on 4th or 5th try. Drove about a 1/4 mile and cut out while driving. Coasted into parking lot and had towed home. Dropped the tank and replaced the fuelpump. Hardest part was trying to get most the gas out...

    '07 Denali hot stall?

    I replaced the battery and haven't stalled since. The last time it stalled, I ran the hazards for about a half hour and tried starting numerous times and the battery went dead. I thought that was pretty weak, so I took the battery in to O'Reilley's and had them test it. They tested it and it...

    '07 Denali hot stall?

    It's not throwing any codes. I've had the Chevy dealer hook it up to the computer and nothing is showing. Even when it has happened, the check engine light has not come on. If I could get it to happen on the dealer's lot, they said they might be able to read something. Any 6.2L owners with...

    '07 Denali hot stall?

    I have a 2007 Yukon XL Denali with 136,000ish miles. On hot days (85+), the engine will stumble and sometimes die at stoplights. Seems to happen when the tranny temp is over 200. If it does die, it won't restart for 45 minutes. The starter almost sounds like there is no compression in the...
