What did you do to your OBS GMT400 Tahoe/Yukon Today?

[the 18th letter]

Got my 2 year inspection done today. I’m good until 26 now and eligible for historic plates next registration in 25.

Check your rules. I can get Historic plates, but that means I couldn't drive it daily. Only parades and special events, or for service.

I was just hoping I could skip inspections with them but will definitely research this further lol

Blower motor stopped working yesterday after making noises for last 2-3 winters where it sounded like a leaf was stuck in the blades. No a/c due to evaporation leak so I don’t use fan much in summer. Think it’s time to take the dash out. I got various dash lights out or dim as well. I’m on vacation the coming week so I’ll see. Can it be replaced without pulling the dash. I’d like to wait until it’s warm

 

[the 18th letter]

Fired up the parts cannon and Swapped in a new fan blower motor. Nothing lol busted up the knuckles a bit and pulled the resistor to swap out tomorrow smh. Thankfully I didn’t need to pull the dash. It got cold today after I started working.

New resistor worked for a second then stopped. I suspect the control switch and will reload the parts cannon and shoot again

Blown fuse?

Blown fuse?

I checked and cleaned the big 50A in the engine bay as well as switched relays and she still started so I ruled those 2 things out. Couldn’t find an interior fuse for the blower, did I miss one.

Here’s the wiring diagram, maybe it’ll help…

Had to use 4WD for the first time ever. Making a three point turn around, I backed into a soft spot. 2WD wasn't doin'; nuthin' but spinnin'.

Pushed the 4WLo button and extended the front claws. Pulled right out.

 

[the 18th letter]

New heat/ac control came in yesterday and I switched them out today and I have power to the blower again. 3rd shot from the cannon successful. Replacing the dash bezel I knocked the rear view mirror loose. I've always enjoyed replacing rearview mirrors, NOT. Also notice now that my side mirrors dont go up and down anymore so more shit to do smh.

What is this piece called that the metal disc for rear view mirror is attached to? If it’s needed what’s it for? It’s like a really thin aluminum pad maybe. (Apologies if a dumb question)

 

[east302]

GM doesn’t show it as a part with the mirror, so it may be something that comes with the windshield to help the glue stick better.

Thanks. Google hasn’t been much help in giving the answer. None of the repair kits I’ve seen come with one either. I was thinking it was part of the mirrors readouts but it would have been on that chart. I’ve never known how the mirror reads the outside temperatures.

You can try posting your last 8 digits of the VIN and maybe @915_Tahoe can help.

That is part of the glass, the plate glues to that to have a better hold.

Are replacements available? Does it even need to be replaced

I honestly dont think its even necessary…it probably helps adhesion and maybe even keeps the windshield from cracking in that spot (ive done that a long time ago) but Ive also glued countless rearviews to the plain glass over the years. Just make sure surface is clean and dry and dont put the mirror on before glue is ready.

Happy New Year
Today I am doing an oil and filter change.
Pretty straight forward.
The filter setup in these is a bit of a pain how it is situated.
While under there i went looking for a rattle in the steering I have been feeling through the steering wheel.
Drinkers side inner tie rod is the culprit.
Felt dry so I've given it a good pump of grease for now and see how it goes on the next drive out of town.
I know I'll need to replace but think it'll do for next couple of trips n will change next opportunity and freshen up the wheel alignment.
