    ABS Light/Parking Brake Light/HVAC Blower Motors

    SOLVED! After scrubbing and reinstalling all grounds did not fix the issue, I checked the ignition switch, which was the culprit. Don't know why I didn't think of that as one of the likely causes to begin with. Installed a new ignition switch and instantly the ABS and parking lights went off...

    04 Yukon wants to stall randomly. What is going on??

    I have the same thing with my 04 Yukon, except mine is when I am idling. It will be sitting at 500 rpm, it will come down to 300rpm, the lights will flicker for 3 or so seconds, then right back to 500 rpm like nothing happened. If I throw it in neutral, the rpm will go right back to 500. I am...

    Coolant leak - Line from AC compressor to radiator?

    After researching it is the AC discharge hose as shown. It is leaking a red fluid from the metal coupling in the middle. The fluid def isn't coolant, it's slightly oily but has no smell like trains or PS fluid. The line does go to the condenser in front of the radiator.

    Coolant leak - Line from AC compressor to radiator?

    Update The line that is leaking is the AC discharge hose, going from the compressor to what I believe is the heat exchanger. Look like just a few bolts and replace. Does anyone have a link to do this to make sure I'm not missing anything?

    aFe intake didn't pass smog -> This was their honest tech help. Lame...

    2004 Yukon 5.3, aFe Stage II intake. Tried to get it smogged yesterday for my registration, passed except for the fact that the shop couldn't find the CARB number for the intake, so it failed. I looked it up, and apparently this intake only has a CARB number for 99-03 even though they advertise...

    2006 Denali Dash Cig Lighter Not Working

    I believe that there are fuses for both the cig lighter and the other 12v power point in the front. Check your owners manual or google 06 Denali fuse diagram and find the right one. My cig lighter blew a fuse and this is how I found out how to fix it.

    2004 Yukon SLE---is my fuel pump dying?

    TB was cleaned at the tune up at 100k...not sure what the MAF is. Does the 2004 have a fuel filter? I've been told by independent mechanics that there wasn't a fuel filter in this model year. @Night Fury...how much was it to replace the fuel pump?

A few times over the past few months, while at idle, my rpms have dropped from about 500 down to 200 and it felt like it was going to stall. I dropped...
