    Liftgate electrical issues

    I have had my 2008 Yukon Denali for almost 3 years now. The rear defroster never seemed to work from day 1. Since then the button to open the liftgate stopped working but will open and close just fine from all other buttons and the fob. Next my rear wiper stopped working. Most recently the top...

    Power running boards stopped working

    My wife took my 2008 Yukon Denali to pick up our kids and next thing I knew she was calling saying my battery was dead. She got a jump from someone and got it home. The running boards worked just fine before she left and have not worked since she brought it home. I did have the battery tested...

    I think I have some Gremlins, anyone know of any fixes?

    Thanks for all the ideas everyone. I did go through the fuses with a fine tooth comb and even replaced a few with new that didn't look blown with no luck. I did get a new battery and new bulbs for my break lights thinking I had one burned out. Found it just isn't working, so I get to add that to...

Over this time a few things have stopped working and they really didn't bother me too much until the latest one yesterday. I don't think my heated washer fluid nor my rear defroster have worked since I got the truck...

    Oil pressure gauge 0 to pegged and back to 0.

    Yes, there are 3 codes causing the check engine light. 2 for oil pressure and one for a dirt throttle body. I should have cleaned it when I changed the TPS last month.

    Oil pressure gauge 0 to pegged and back to 0.

    My oil pressure gauge is going crazy. It will sit at zero then spike up to the top then quickly drop back to zero. Is the gauge going out? Is a sensor going bad? Any ideas? Here is a video of me driving down the interstate today.

    Tire pressure sensor going crazy!

    I was driving down the interstate a few weeks ago and my Tire Presure warning came on saying my pressure had dropped to 1psi. I immediately pulled over to check and the tire was fine. Ever since i can watch it tell me my pressure is anywhere from the 90s to 0psi and it fluctuations all over in...

    How did you deal with rust?

    I have a 2008 Yukon Denali that I purchased about 6 months ago. I've noticed there is rust forming on the bottom of the hatch and the bottom-rear of the back doors. I can see why since the back edge of the door is basically the edge of the wheel well unlike if it was an XL. What have you done to...
