    Non-functioning lumbar - fixed with my own 3d printed parts

    I figured I'd post an update. Unfortunately after about 3 weeks, the lumbar seemed to not function again. Opened up the gearbox to find broken parts. I'm thinking it could be a combination of things. I printed these with PLA which has a low melting point of most(if not all) the 3d printing...

    Vibrations

    I had a vibration at 45-55mph on my ’07 Yukon that appeared shortly after having the 6L80 replaced at 191k. I first thought it was most likely the tires so I had them rebalanced and rotated which seemed at first to do the trick but was not the case. I suspected the new reman’ed trans next since...

    Non-functioning lumbar - fixed with my own 3d printed parts

    My lumbar has not worked in my 07 Yukon Denali for the past few years and I had pulled the seat to investigate a fwd/aft binding issue. The lumbar would move up and down but not in and out. I could hear a clicking in the rear of the seat when attempting to operate the lumbar motor but there was...

    07 Yukon driver's power seat help?

    I've got a similar thing happening with my 07 Yukon driver's side. In the most forward position it seems to operate fine but as the seat is moved back it acts like it is binding. I removed the seat, disconnected all the connectors from the memory module underneath the seat and jumpered 12V from...

    Is there some digital kill switch I can put on my Tahoe?

    Maybe check out the Digital Guard Dawg DGD-M1.

    Cleaned Throttle Body Now the RPMs are too High -- 07 Tahoe

    I cleaned the throttle body on my '07 Denali last year and even after the initial relearn procedure, it took at least another 1000 miles of driving before it was completely back to normal. Before that, it would idle itself up to about 30mph from a stop in gear and it would feel like you were...

    Door handle swap

    I believe the letter C in the part number (941C for the fronts) denotes the chrome option of which I have so I cannot comment on the nonchromed option.

    Door handle swap

    I am really happy with the billet aluminum replacements. They feel much more solid and sturdy when you pull on them.

    Door handle swap

    I replaced mine as they broke with billet aluminum handles. I believe the manufacturer is "All Sales Manufacturing". I first replaced the rear handles(part# 942C) a few years ago and just got them off Amazon for under $300/pair. I just replaced the fronts (941C) a few months back and got those...

    Whats the difference between 07-12 and 2013 headlights?

    I'll throw in my 2 cents on my decision I made back in December for my '07 Yukon Denali regarding this topic... We had moved out of town about 10 miles and into deer country and driving at night with the stock headlights was almost a death wish. I needed better light output and seriously...

    6.2 L92 Volumetric Efficiency

    Thanks for the replies back. I'm not attempting to tune but was trying to figure out what the expected airflow should be to see if the MAF was the root cause of the 3 trouble codes I was seeing. I was trying to correlate airflow to throttle opening to engine speed but the 3d plots in Excel...

    P2101 and Throttle Body Vibration

    I, as well, have been dealing with codes similar to yours, P0121 (throttle circuit performance, P0171 (Lean bank 1) and P0174 (lean bank 2). I believe I have mine fixed for now by cleaning the MAF. However with the codes and description you give, I would suspect the throttle body too as you...

    6.2 L92 Volumetric Efficiency

    Sorry this post got longer than I was planning.... So I've been dealing with a few error codes the past 2 months... P0121, P0171 and P0174 on my '07 Yukon Denali with 113k. Vehicle is completely stock besides a K&N air filter that I've had on for about 60k. There has been no engine work ever...
