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

[Rocket Man]

Nah i’ve already disabled that thing. Bearings in that fan are destroied.

It does go away when turned off, and doesn’t change pitch so much as it just makes a slightly different pattern of noises at different speeds

What do you mean you disabled the adpirator? It’s kinda important even if you don’t use auto.

Came home from being gone for 2 weeks. Battery was completely dead, couldn't even jump it. Wasnt even a year old.

That sucks dude.

You’re the second guy here that came home from vacation to a bum battery. @CHOO CHOO had the same thing happen to him recently.

Exactly the same. Ended up buying a new battery.

Advance Auto gold battery was $135 with a 25% off online coupon and core charge refunded.

Had this for about 6 years. Probably time to get another one cause it shouldnt look like this.

I unclipped it from its mount and flung it away from the vent on the headliner so I can’t hear the rattling laptop fan that its got on it

How so?

How so?

I think maybe it samples air temp to fiddle with blend doors even in manual mode but I don’t know. What I do know is the heat works when its cold out and the cold works when its hot out

 

[Rocket Man]

How so?

I thought it’s part of the interior temp sensing.
I mean, it IS the interior ambient temp sensor....the fan is there to pull air across the sensor. I’m not sure what the vehicle uses for interior temp when you remove that but I guess if yours still works, great. Probably not as accurate IMO. I am in the habit of fixing stuff not tearing it out.

It doesn’t need to sense the temp if its not in auto mode though.

Don’t you set a temp? Or does yours not maintain a set temperature? That’s what it’s for. It doesn’t necessarily have to be in auto mode to need to know what the cabin temp is. I don’t have any vehicles without at least temp settings. IDK, I leave mine on auto and the only thing I do myself is change the blend setting. I never touch fan or temp. I guess I could leave it on full auto but I like just a little control.

Not sure. I set a number but i mean I dont have a freezer thermometer sitting in the console to know what cabin temp is. I always figured ‘60’ was all the way in the blue on old style HVAC controls and ‘90’ was all the way in the red. The change in the sun going behind the clouds will effect how hot it feels in the cabin more than it will the outside air temp changing 3 degrees.
