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

[iamdub]

Tozan and I are trying to figure out how to put a switch on the inside of our trucks to release the tailgate from the inside. He has a great setup in his rig for camping, attempting to do the same for us here. His whole link is on the suspension section. Frigging awesome stuff.

Couldn't you just run wires in parallel off the circuit to the button (more like a squeeze pad) in the handle to a pushbutton on the inside?

Did you consider doing the Inoperative Liftgate Modification?

What about getting another FOB and velcro it somewhere on the interior?

What socket do I need for the oil pressure sensor?

The oil pressure sensor socket. I’m not messin with ya either.

Bad ground lug at the battery? Lol

what is it this time?

I wish it was a bad ground. One problem is that same one I’ve had since I swapped the Tahoe dash in- Driver side airbag deployment loop open or short to ground. I have beat that one to death but thought if I pulled the entire dash again I might see a pinched wire but nope. I needed to pull the dash anyway or at least so I thought, to fix the new one which I found when trying the ac for the first time this year. It’s B3933 AC evaporator temp sensor circuit open or short to battery. That dtc doesn’t even show up in my alldatadiy. I ordered the sensor and the videos I watched show it and the solution is complicated but it’s supposedly easiest if the dash is pulled. I can’t even find the damn sensor or the wires going to the sensor. It’s not where the videos show it to be. And some GM dealer parts sites don’t even show it. Alldatadiy only shows the time to replace it, not how to or where it is. It won’t allow the compressor to turn on. All this work tearing my truck apart and no luck at either problem so far.

The fob only releases the glass portion, want to be able to open the entire lift gate from the inside.

I take yours does not have the overhead console switch? not sure how much plug-n-play it would take but you can buy the console portion on ebay for about $50 with the switch, then I guess wire it up? mine has the denali trim but I would assume they all would have the inside button on the side kickpanel in the back

My truck is a SSV, limited on the extra pleasantries, but that’s why I bought it.

I am itching to be able to get to a recycling yard with these trucks in there. They thankfully haven’t hit that time yet. Have tons of things I want to get for this truck.

The switch will be awesome, I just have get to the wiring and make it happen.

The dogs are an awesome addition, I hope the rest agree. Really miss a furry four legged ******** in this house. The cat is good but a howel bellow is missed.

Awesome. I’m officially pissed at GM. After tearing the entire dash out of my truck to replace my ac evaporator temp sensor to fix dtc b3933 I found out from a TSB that I don’t have such a sensor in my truck, the replacement HVAC head unit I installed last month needs to be programmed via TISWeb and my Tech2 or that dtc shows up and the ac won’t work. No wonder I can’t find that sensor.

View attachment 248258 This. Again. Chasing a wiring gremlin.

Red, theres some rust on the dash supports, you should wire brush, prime and CM.... just sayin the dash is out so much at least it will look good While its out next time....

At least you were able to finally figure it out.

Not a pit thing. My jack Russell Porkchop does that when its really hot out. Our Heeler does it too. Zeus the collie does not. But hes old.

Also. My bad. Turned this into show your dog's. Haha

New rims and tires mounted. Of note, OE Wheels is loaning me a TPMS tool and their expert is going to troubleshoot the new TPMS sensor issues with me... pretty cool! Hoping it works so I don't have to replace them.

This is exactly how I do it. I watch for it to start sputtering, shut it off, add more fluid, start it back up and repeat. Usually takes about a full wasted gallon before what's coming out looks identical to what's going in.


Here's the first video I Googled. This Hotel WiFi is kinda slow, so I just skimmed through it. Not totally sure of the content/relevance:

Yall use power steering fluid or atf?

When i swapped my rims out, i got the same issue. One tpms senior went out, then all the others went out. Relearn tool only worked on the firsr wheel

Atf is thicker and prob not good for newer cars, id stick with ps fluid. I had a few cars Years ago that had leaks and atf was cheaper and lasted longer.

aaah this is how I had my crash course in how the rear hvac works in the yukon xl, after I tore it all apart and tested this and tested that and found a very much non-existent wiring diagram to discover my truck does not have said "sensor" and the rear ac wouldn't work, same issue controller needed to be programmed to my vin

in the process I spent hours on it and replaced a $125 actuator that was fine

Borrow one from VatoZone
