    Blend door actuator

    On my 2004 Yukon xl the drivers side acts up sometimes. It will start blowing hot air. I can turn it off and start it back up and it works fine after that.

    P0156 code

    I’ve just started getting the p0156 code. I haven’t seen that code very often when doing a search. From what it looks like it’s the O2 sensor bank 2 sensor 2. I got the code and had it on for about two days then I cleared it just to see if it came back. After a day of driving it it came back...

    Gauge cluster question

    My 04 Yukon Xl has just started randomly scrolling through the option to change the language. Then today it was acting as though I was scrolling through the different menus. I have the buttons on the steering wheel to select the different options. Are there anything I should start to look at...

    New head unit for 04 Yukon Xl

    I'm looking at replacing my factory bose HU because the CD player doesn't work and I would like to add a backup camera. I've been looking but can't seem to find what I'm looking for. I haven't had to buy an aftermarket radio in about 10 years so I'm a little out of touch with it and don't know...

    Looking for a obd reader that's iPhone compatible

    I've just started looking but think it would be a valuable thing to have. It needs to be iPhone compatible and also what app are you using.
