Well, it turned out to be a cracked spark-plug on cylinder 6. When I got home I used auto doctor and there was a pending code that was not there before. A week ago I was installing a manifold clamp (don't judge) in the area and when I "moved" the dipstick tube out of the way I bet I levered it...
Hi there, I have a 2004 Yukon XL 5.3 auto 4x4. At a stop light, in drive with brake applied it surges. Thought it was missing but it’s not. If I shift into neutral it stops. Never had an issues before. I recently started using Auto 4x4 for the first time in the ice, but it is doing this in...
My 2003 Yukon has gremlins and maybe you can help me out. AC works great blows super cold sometimes for 10 minutes, sometimes for two hours, then it start blowing hot air, again sometimes for 10 minutes and sometimes for an hour, and then it will blow cold again. All in the same trip. This is...
Great questions. Yes they are multipurpose and they do work as markers. But not 4-way flashers. However the left side of the care flashers do work on 4-ways.
Hi there, after hours of diagnostics I am going to see if any you guys can help me!
I have intermittent fast blinker right hand side. When it blinks fast only the mirror light works and blinks fast. Front and rear do not work at all. It will be bad for days and then work for 10 minutes...
Hi there, I watched a bunch of videos on people installing Dorman 917-107 exhaust clamp on the rear drivers side exhaust manifold. The videos were less than helpful, so I wanted to share a little advice that will save you hours of cursing and scratching your head.
1. Drop the front of the...
I'm posting this as a solution in case it is helpful for someone because it was bear to figure out. Rear wiper was not working and made a humming or buzzing noise. Almost like a bad motor. Fuses and switch ok. Took motor out, looked okay but ruled out everything else so I got a wrecking yard...
Great feedback! I lucked out and didn't break anything, but I have a brush guard that took some of my weight. I also took the cover off. Mostly my weight was on the front subframe. But great call that people should use caution when laying on the engine compartment. Lots going on in there.
I just swapped mine out using a wobbly and two extensions. It took 10 minutes start to finish. I put a rubber mat in the compartment and laid on it so I was looking over it. It wasn’t easy, but it wasn’t as hard as I thought it would be. Actually I spent more time worrying and watching...
Hi there, you are correct. I found the schematic and as a result opened up the fuse block. Looks like the hot leg was broken at the circuit board inside the block (you can see it wiggling in there). The leg feeding the TCM was fine. So rather than taking it all the way out, soldering it or...
Mine were really in there is well and when I finally got them out there was some crazy pink thread locker, although I think they my have used JB weld instead... I used a 24 inch breaker bar and an impact socket, and applied a significant amount pressure. My Dewalt impact with 4amp battery is...
Thank you. Yes that is my plan for the day. I was hoping there was an easier way, but I suspect your right. I will follow up when I track down the issue...
Hi, thank you for the reply. Yes that fuse is fine. Also If I jump a wire from the battery to the 30amp TREC fuse my 4wd lights up. But there is no power to the trek fuse, and the schematic looks like it should have constant hot. I attached the schematic I have.
Hi everyone, I have a 2003 Yukon XL 5.3 4wd. From what I can tell I have a pretty unique issue.
When I bought it someone had jumpered a wire from the prime port (aux power for testing) to one leg of the TREC fuse so the 4wd would work. I figured this out when I tried to put it in 4wd and it...
