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

Two things =
Its nice to be able to get in and out of the Tahoe without hearing that ridiculous grinding from the jacked up door pin.
What a relief to not hear that clunking in the steering after replacing the ISS. Lock to lock without a grind or a clunk, nice.

I thought I was

I think you’re an influencer if that helps.

It’s definitely the little things sometimes that can make a big difference.

Actually no idea, 15” rotors and caliper spacer

that's part of it, what about the calipers?

My guess it wont open no matter what you do until the wiper motor is replaced and wiper arm is installed properly in the parked position, it's a safety interlock so you can't open the rear glass and then whack yourself with the wiper arm in the process.

Sounds reasonable. I will pull everything apart again and plug the motor in to confirm. I may have to “phantom mount’ the motor in the door panel somehow until I can get my hands on a wire diagram and find a way to bypass it.

that "might" work IF the wiper was still in the parked position when you unplugged it and if you don't accidentally turn on the rear wiper and throw it out of whack.

Theoretically the motor should return to the self park position by itself shouldn't it? Of course we are getting thunderstorms so this should be fun.

without the parking stop being there not sure, people have had problem with the rear glass not opening and it is usually because of the rear wiper not in the correct position, happened to me on my nbs these are the same design mechanically.

I am going to investigate the wiring from the push button and the latch solenoid and see if they run into the wiper plug and if I can make any sense out of it or bypass it.

But I will plug the motor in first and test everything to confirm our theories and report back. Thanks for the help and brainstorming.

Were you able to figure it out?

Working on it right now brah. Here is the wiring plugs. The blue and the pink with black stripe both go to the wiper motor. The red with white stripe on the wiper plug is power black is ground. If I run a jumper from the red/white to the blue the glass solenoid pops open. Really need a wire diagram.

Ok when I run this jumper from tan to blue on the wiper plug it works. The button and the key fob open the glass. Not sure what to do with the pink/black wire for the glass ajar signal.

 

[89Suburban]

That jumper wire was the ticket, everything works right, rear access warning works, all good!

Do you get the window ajar message? If so maybe try putting a jumper from the pink/blk to ground--maybe that'll kill the signal?

Nah I think it’s all good man. Warning only comes on when it should. Tailgate open or glass open. No warning when all is closed. I think I got it.

Quick question:
How long ‘yall going between oil changes on Mobil-1?

I am at 4,000 and down 1/2 quart. Oil still looks golden color.
