    Can I use the “better 2011” hydroboost?

    Can I use the 1781036 hydroboost unit (2011 MY only 2500HD)? Supposedly this is a better unit than the others. I have seen many use it on there gmt800 Duramaxes, just wondering if anyone has done it on a Tahoe or Yukon? Sounds like you’d just have to enlarge the hole to fit. My truck (05...

    Already changed the mode door....

    Good luck! Mine still gets stuck on one mode every once in a while but always fixes itself the next start lol. I had the evap code, ended up dropping the tank because the all the lines were packed with charcoal pellets all the way up to the purge lol.

    Already changed the mode door....

    No prob. I definitely had fun doing this thing-installed the gear incorrectly the first time and it was wonky. PITA!

    Already changed the mode door....

    Maybe I’m wrong, but I’m pretty sure the one that requires dash removal is for recirculation. The mode one definitely does not. I just replaced that one not long ago.

    Tpms tool

    Just used my tool after a tire rotation yesterday. Worked perfectly again. I did notice the 9 volt battery has to go in “backwards,” the friggin + and - are labeled wrong on the tool lol

    Key fob low message reset

    I got the key low battery message yesterday on the DIC. Replaced battery. Still got the message after several trips and trying a (tested) new battery. Found another forum to turn the key to on and press unlock button on the fob when the message comes up, seems to have done the trick. Strange...

    Brake Control Module-Solved

    If it’s abs and brake lights, almost assuredly the module under the driver door on the frame. Replace or resolder it. Easy. Well, maybe not if you live in rust belt to get the torx screws out

    New GM ISS = more slop?

    When I did mine I replace the “bearing” (plastic thing) also. The first one I got was junk and worse than the old one, it actually fell apart. Replaced again and it was good to go.

    Window regulator brands that aren’t junk

    To follow up I used “FFS” brand off of Amazon for less than $40. It works. Hopefully it lasts for more than a year or two.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Fixed the right passenger side window burned out motor with a whole new el cheapo regulator assembly ( $37) Not too bad. Kid will be happy. Gee, wonder why it was that window. (200,434 miles).

    Window regulator brands that aren’t junk

    What do you guys use for window regulator/motors assembly in the gmt800s. Right rear window died yesterday. First one to die on this truck at 201k. Rock auto doesn’t seem to offer GM or AC Delhi for RR. Aisin stuff is usually good. Would it be worth the $90 vs $36 for “whatever name”...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Started it up this morning to go rent a lawn aerator. Massive annoying loud whine through the stereo (left speaker only). Was really annoying. Thankfully disconnected the large connector under the cup holder and reconnecting it solved it. I’ll probably disconnect it again and spray some Deoxit...

    Electrical - where to begin

    You can at least check each one for resistance with your multimeter. You can do a rudimentary function check since they should create AC voltage also. Maybe your meter has a “remember peak” setting and you can test each sensor and compare. Keep in mind your results could be the knock sensor...
