    Brake lights out

    This looks like the split between the center mount stoplight and the side stoplights. UBEC is your underhood fusebox.

    Remote Start Troubleshooting

    Here's a video with some info.. Sounds like this guy had an engine code that prevented it from starting, but he does go over some requirements for remote start to work.. Also seen a thread about a bad hood latch wire which prevented remote start. Looking at the diagram below, it appears...

    Suspension issue? 08 Tahoe 204k

    Occasional clunk? I'm guessing Balljoints. I had a bad one that wouldn't clunk so much as chirp a tire when making a tight turn..

    Wiring diagram complete

    https://www.gmupfitter.com/light-duty-vehicles/light-duty-prior-to-2013/ Some of the later diagrams don't include the stuff from earlier years. I find myself using the '08 wiring diagram for most things (latest complete diagram I can find)...

    Rear end gone???

    Exactly. It is just another differential between your front and rear driveshafts. In the 4WD tahoes, there is no diff in the xfer case, it just locks front and rear together. Rear is always connected. An AWD sytem with all open diffs could potentially(theoretically?) get 3 wheels stuck and spin...

    Rear end gone???

    So you did pop the driveshaft out of the transfercase before/as it started rolling? Because it could have been bad if still attached to the transfer case when you told her to hit the gas... Reminding me of a video where a guy's jacket sleeve caught and sucked him into a big lathe.

    2013 no crank.

    You can buy a tech2 clone for ~$400. He might be using a newer scanner, but the tech2 will do everything available for our trucks.. in case you get more issues in the future.. Good luck and keep us posted!

    Rear end gone???

    AWD differential? Similar to lifting both rear wheels off the ground in park, but you can spin the wheels.

    Dimmed Backlit Dash and Radio/HVAC Lights

    It's not too bad, but you risk breaking some clips forsure.. Every morning lately the dash is dim. Bright enough for sunglasses (cloudy) but my dash is dark. I will be happy to finally wire a switch, I'm just looking for a good 3 position dial ...

    Dimmed Backlit Dash and Radio/HVAC Lights

    I removed my front panel to pop the sensor out.. definately not accessible from below or through the radio hole..

    Sounds and feels like driving over rumble strips

    I think your trans is still cold, there is a dic display that shows trans temp. I think 160F is warmed up... Usually takes me about 15-20 minutes of driving around.. If it hasn't ever been changed, it's a good time to do it. Even though I thought my oil looked decent on the dipstick, the first...

    Sounds and feels like driving over rumble strips

    Guessing it is a blown motor mount. I had a bad one, and it oozed on the front diff much like yours. Not sure about the rumble strip feeling.. tcc slipping?

    Wierd noise

    tensioner/idler pulley are in the area and worth a check. (cheap and easy to replace!)

    Stupid Cylinder 4 misfire 304

    Good time to check the plug again too.. I once cracked a plug during installation.. Though it sounds like you probably changed all the ignition stuff chasing the misfire..

    Does my radiator have an engine oil cooler?

    I ordered one before. The plate/block is part of the lines. The gasket and a bolt? are included too..

    2013 no crank.

    Someone here recently had a no start issue that was related to the relay. Ended up being no ground to the relay socket, which ended up being a bad fusebox! (There was a bubble/break on the pc board) https://www.tahoeyukonforum.com/threads/07-lt-5-3l-sudden-no-start-crank.151033/page-4 You might...

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

    Alright, I think I know.. So the hose company can sell more hoses! That's where the term "getting hosed" comes from!

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

    Sounds good! Although on my Tahoe the heater core connections are both on top tank. Looks to be partitioned and flow in a 'U' flow pattern.

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

    Have heard that too! But then, what difference does it make if it's backwards when the hoses are the same size? It goes through the heater core backwards? Shouldn't matter?

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

    Lots of cars have been like this for awhile. Not sure exactly why, but probably to help with the flow. Larger hose on water pump suction side. Have heard mention of it minimizing gurgling sounds in the core. idk..

    A/C compressor cycling on? Or worn balljoint maybe?

    Tire Noise Reduction -- Any Experiences with Fender Liner and/or Fenderwell Treatments?

    Maybe rhinoliner or similar on the bottom/front of the cab, definately put something in the rear wheel wells. You can really hear the road noise with the interior panels off in the back. The factory put some caulk deadener on the inside of the rear wheel wells already. Maybe more jute padding...

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

    That clamp can come off and be re-used! Just stretch out the clamp tab a little with a mini screwdriver and it will pop apart with some massaging. I used a mini end cutting pliers like this one to tighten it back up. Is the bushing stiffener noticeable?
