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

    Check the lighting block connections for corrosion (it’s near the rear wheel wheel passenger side). Mine had green crap in one connection, and it caused all kinds of weird turn signals crap. Cleaned it off 4 years ago, fine since.

    2006 gmc yukon xl slt plus gauge cluster.

    He has quite a few videos about our clusters, adding the trans temp etc. sat in his shop while he added trans temp and turned it on for me. While I was there, had him redo all the steppers, change to LEDs and put white face Escalade in. Now my turn signals light up blue lol

    Oil Filter Leak? Maybe?

    I’m betting valley or main, but I’ll crawl up there one of these days and recheck. Wouldn’t be surprised if I didn’t get it tight enough or something since working blind back there

    Oil Filter Leak? Maybe?

    I’ve been chasing a drip on the inside starter bolts for like 3 years lol. Mechanic said it was “definitely” the rear main. But that inspection cover off, dry as a bone. Who knows.

    Reprogramming mileage and VIN you need the right software and EEPROM computer. Not something the average guy is gonna do himself. People who rebuild them or work on them usually can do this. Just don’t ask them to fake the mileage, it’s a felony. I’d think you’d have to have proof (your old...

    Abs and Parking Brake light

    Yep, Ive fixed mine twice. Not sure if it was a different joint that I didn’t fix the first time, or if I just suck at soldering. But it took 2 years to break again lol.

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

    Rocket man’s comments made me run 3 quarts thru, pumping it all out. Somewhat better. Probably just gonna have to replace the pump one day. It’s been a little groan noise when turning hard left in parking lots for years.

    Btw the new pump I got from rock auto was redesigned, I believe the float is now in a slightly different area. Worked fine.

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

    Plugs and wires and attempted to quiet the power steering with a turkey baster and bleeding it. Still groans some. #8 plug was a PITA, finally figured out the best way was just to lay on top of the engine, then it was easy. Old plugs didn’t look terrible, maybe somebody did them in the 145k...

    Dying on idle.

    My fuel gauge would go to empty just parked on a slight decline. That stopped after I replaced the fuel pump. Pretty easy in the driveway with jack and stands. I used a second jack and some wood to hold the tank up. Make sure you disconnect all the lines, there’s several.

    Finally replaced the driver side blend door actuator that I’d had sitting for 4 months. 3 years ago it turned hot once, I took it apart and cleaned etc. worked fine until a couple months ago, it did it once. This week it happened 4 times, so in the new one went. Old one still clean this time...

    Trouble filling up the gas tank

    I think this can happen to just about any car of you keep putting in ore gas after it clicks, fouling the canister. Just let it stop and be done.

    Trouble filling up the gas tank

    Even if gauge is wrong, it shouldn’t spurt gas out before clicking off the tank...

    Abs and Parking Brake light

    Definitely do the resolder of your abs module, Dry common and it’s a basically a free fix if you can solder
