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

[cooki3mnster]

once the gauge is added the eprom on the cluster needs to be flashed to make it work, the sensor is already in the transmission on all the suv's and pickups. In addition if you swap the cluster in from another vehicle it needs to be programmed for you vin & mileage, one may work by just plugging it in but it may work properly until it is programmed to the vin

Thanks, I also reached out to Digital Dash Solutions and he confirmed that once the cluster is programmed it is PNP.

Also just noticed you're in Stockton. Im just south of you in Livermore.

If it doesn’t work all you need is a flash but I’m not sure what needs to be flashed, don’t you know Tony?? Isn’t it the cluster itself ?

If you get a cluster that already has the trans temp gauge, it should be good to go. But if course, you’ll want to have VIN, mileage, etc.. programmed.

I was late to the party. Lol.

What was the issue you were having? Was that under "Special Functions"?

My recirc. door doesn't move at all and Tech2 gives DTC B0229 - Recirc. position feedback circuit range/performance. I'll have to double check, but you go under BCM/HVAC and can look at DTC's and perform Door position tests. Everything looks good, except the recirc. door doesn't move. Hoping it's just the actuator and not the door broke or a short in a wire. When I press the Recirc. button on the control head it stays lit up, but the door doesn't move. No clicking sound or anything.

why take the dash off? as far as I know you can get to it up underneath from the drivers side, that is the hardest one though

Recirc door actuator is behind the airbag on the passenger side.

the actuator behind the airbag is the passenger side hot/cold blend

Here is what I’ve read. See this: https://sparkys-answers.com/2010/08/changing-recirculation-fresh-air-door.html

passenger blend door actuator is under vent up beside radio. The one by the drivers feet is the mode door. The one by passenger feet is drivers blend door.

you should be able to get to it with the airbag out then

That ones hard. I did mine by partially removing the dash ( the actual dash, not just the cover) and prying it up with a piece of wood to give me just enough room to unscrew it. Service manual calls for complete dash removal, about 6 hrs or more to R&R. Good luck.

Document parts, sources, process and lots of pics! Then I'll copy you since I copied the airbag.

Hell yeah! Might be a while though. I didn’t realize it’s less pnp than I expected. Lol.

NNBS, but pretty much same results. Mine is a 2003, and is a DBW. I have to figure out the fuel rail, 2 pcvs, some wiring.. a whole lotta stuff..

Got the Recirc. door actuator replaced. PITA. Still need to put dash back together in the morning, but everythings working. Didn’t end up needing to cut duct. Removed dash cover and airbag along with Onstar box. See 2nd pic with 2x4 raising duct just enough to get hand in there. Barely.
