    Heater quit working/blowing

    Front blower motor and resistor are under your glovebox. Need to remove underdash cover (3 screws, one near the middle) When you take that cover off, you will see everything.

    2008 Tahoe LT VCIM Swap

    Even with the two bolts out, the bracket just falls down a little which didn't seem to help.. Not much space to lift up before it hits the dash, some people cut the dash part above it. I cut my VCIM bracket because I eliminated the VCIM and no longer needed it.. (May have cut it just to remove...

    Help having electrical issues

    Flickering lights and things going on and off could be a gound/power issue. I would clean any grounds you can find and inspect the battery cables for corrosion/tightness. If misfires on 1&4 only, perhaps worn plugs or bad plug wires or bad coils? Swap them around and see if misfire follows.

    Lift gate assist buttons and the issues im having.

    The diagram shows the switches wired in parallel I believe... So you can make both switches work, but not when both are plugged in?

    Aluminum / XFE NNBS Front Suspension Rebuild

    I swear my x_tracker hubs groan when you lean into them a little.. Had them about a year, no real issues, just not convinced they're better than stock..

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Definately want the bigger hammer! I was flailing away until I changed to bigger hammers. I like to use two hammers and hit simultaneously on opposing sides.. But, when you get tired of flailing around, it's not always synchronized. I did in at least one of my upper balljoints.. Thinking...

    Another Lift gate problem (Broke again!)

    Is it not opening because it thinks it's already open? Maybe something to do with the liftgate sensors? I think @Doubeleive has pictures of them. https://www.tahoeyukonforum.com/threads/what-did-you-do-to-your-nnbs-gmt900-tahoe-yukon-today.44151/post-1951886 Here's a thread that shows the...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I have a short 3/8" breaker, comes in handy. Sometimes a ratchet head won't fit, and it's adjustable angle. I swore never to buy parts store tools after a 12point socket cracked and rounded a head bolt.. I ran out to buy it just to remove that head. (also autozone!)

    9L7 upfitter switches

    I connected wires 1, 3, 7, 11, 13. Don't need #13 if you want your switches powered all the time.

    AP8 -REMOTE VEHICLE STARTER PREP PKG

    According to this thread... https://www.silveradosierra.com/threads/remote-start-ap8-questions-issues.722217/ AP8 just means you can get remote start working, but you need an 'activation code'.. I wonder if they just flash your BCM. Apparently the 'kit' to install remote start even includes a...

    Stutter - Rumble

    Set your cluster to display V4/V8 mode. See if it happens mostly in V4 mode.. Might be your AFM activating, and/or your torque converter slipping.

    Power Lock Issues

    So putting truck in park always unlocks all doors, but using the remote, passenger front and driver rear unlock intermittently? I'm guessing those actuators are having a tougher time with lower voltage when truck is not running.. (need lube as doub said, or new locks) Driver switch, you might...

    Engine repair

    If it's not been overheated, and surface looks good. I would just slap it on there. I figure the more work done, the more potential for a screwup. But I'm just a backyard mechanic... I could understand a shop wanting to do that if they have to warranty their work. Other thing is, they need to...

    Have 2007 Tahoe ltz 189k leveling kit in front end suspension feels mushy wallows a bit ..

    How tall of a spacer? I feel like the 2" lift is about as high as you want to go. (with Z71 suspension) I tried 2.5", didn't feel good. Bottoms out on full extension too easy. I went to 1.5".. Might need an alignment as well.
