    Glitter in 6.2L oil ... please help

    I'd look at a used junkyard engine. If you're handy you should be able to swap them out. If you have a local junk yard they may offer install but of course, at a cost. To get all of those flakes out of the engine will require a total disassembly even if you reuse parts. A guaranteed used engine...

    Battery Voltage Fluctuation

    I've had my Yukon since 08/24 and the voltage has always sat on 14. Then I had the issue of a dead battery after sitting for 3-4 hours.This turned out to be the Instrument panel cluster IPC. It was keeping half the truck awake and drawing 7.35 amps. Dealer replaced and programed the ISP and the...

    I have the same problem with a 2017 Yukon XL Denali. I just ordered the LCD screen with touch pad for $80 on line. Probably get it put in on Monday and I'll report if it fixed the problem.

    2017 Yukon XL Denali 7.32 amp draw

    went to the dealer today. Gave them my notes. Tech was able to run it all down in 2 hours. The draw is due to the IPC and they are on back order with no ETA. The door lock issues are the 2 door lock switches inside. The seat heat is the heater module under the front passenger seat AND the module...

    2017 Yukon XL Denali 7.32 amp draw

    Fless, I'm sorry for the delay, but...life. I have an Autel Maxicon MK900 that I'm trying to figure out how to use. If someone knows of a good class or video I'm interested. After all the testing and battery disconnecting every time I went some where, there were items with codes and some with up...

    2017 Yukon XL Denali 7.32 amp draw

    I have a Fluke clamp on amp probe and I'm grabbing both neg cables. I used an in line 10 amp Fluke meter and they were very close in readings. The reading varies slightly all the time when it is drawing over 7 amps. I am measuring the fuses in millivolts and checking the power probe charts. This...

    2017 Yukon XL Denali 7.32 amp draw

    I've had this since August. When I got it the seat cooling fans did not work. The dealer had them fixed. A couple of months later I noticed the heated seats did not get hot. The buttons and lights do what they are supposed to but no heat. Then my wife says her door won't unlock. I tried my...

    ABS and Traction Control Light Comes on and Goes Back Off

    I got a chance to scan mine today. The wheel sensors all tested good but the EBCM failed the test. I saw the idle voltage going to it was 0.2V. When I turned on the pump it made no sound and took only 2-3 seconds to fail the test. It said, the pump was stuck. There is a motor in there and...

    ABS and Traction Control Light Comes on and Goes Back Off

    I just got the same issue on a 2017 Denali. I have no CEL but I pulled codes and cleared the old ones. No active codes and old codes were, miss fire, O2 sensor, O2 heater. I'll put the bigger scanner on tomorrow and I expect to see a wheel speed sensor tripping the ABS light. The cruise and...

    Has anyone upgraded 110 volt outlet in console?

    2017 Yukon XL Denali. It has the 110v outlet in the rear of the center console and it works fine. It is 100 watts according to the specs. Has anyone upgraded theirs? I'd like a 500-1,000 watt outlet. I know they make inverters in this range that plug into the cigarette lighter ports, but that's...

    Dome lights have a mind of their own

    To anyone else that read this thread to a no conclusion....The tech bulletin was for only 2015 if I remember correctly. I have a 2015 and the rear dome lights flashed one time for .5 seconds when you hit the brakes on mine however the tech bulletin mentioned some vehicles would do it with a left...

    2017 Yukon - Blinking headlights, but alternator and 2 batteries working fine

    Do you have capacitors installed near the amps? They will stop the voltage surge at the battery. The recharge in micro seconds and are not like a battery. If not add a 5 to 10 Farad capacitor. You can go bigger, it won't hurt. When they added cables for the amps and battery did they take the...

    2015 GMC Yukon Denali A/C Concern

    The dealer must have replaced the accumulator/dryer and orifice tubes. If there was any trash left in the system the accumulator should catch it before it returns to the compressor. I have done the same repair on many vehicles. None came back that I can remember and one ran cold for 9 years...
