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

[Tonyrodz]

Nope, manual fold, heated.

Searched online and looks like the spring nut clip thingy has popped off and I have to remove and disassemble the mirror housing and punch it back on. I'm just having a problem getting the mirror glass snapped off.

How hard is it to change the painted cover on one of these? I found a complete replacement mirror but it has a red cover and mine are pewter (gold).

Easy--just stick a plastic pry tool and pop it out. Held on with tabs and a little double sided tape.

My 01 used to do this, I fixed both sides. Push the mirror all the way to outer position and look in, there are tabs all the way around The circle part holding glass on, using a Long pocket flat head screwdriver Snap each tab off the circle part( sounds harder than it is, when you get a 1/4-1/2 way around It’ll start to pop off, watch the wires for the heat, soldered tab breaks sometimes. From there it’s simply unscrew 5-6 screws and the housing comes off, do it off the truck, easier. You can basically disassemble the entire mirror on a bench. To fix mine I used a hack saw blade to enlarge the ring around the shank that holds the spring and push nut. After you clean up the ring and make sure the tabs on the push nut are flat using 2 large flat head screw drivers on either side push down on push nut (Mirror on the floor now is easiest to work with now) and it will catch on ring on the shank. Easier than it sounds. Put it all back together.... done
Easiest is buying a used one.

Yes. They're the steering wheel controls.

Oh, lol. Honestly since I don't have them I've never noticed before.

I almost forgot what those look like when they aren't all worn off. I can barely read what my steering wheel buttons are, haha

They were on ebay. I was looking for the bottom left button because mine does not work and I came across these. No details on what they came from.

Discovered cracked Castech heads right at the start of the COVID lockdown (mid March). Ordered a pair of refurbs from a place in CA that got good reviews. One was a castech, the other not. Took my sweet time installing, some weeks I wouldn't even work on it. Buttoned back up mid June and drove less than 500 miles by mid July. Noticed coolant level still lowering...not good. Emptied new catch can - milkshake. Pulled valve covers - milkshake.

Depressed and dejected, I let her sit until this week. I didn't know at that point if I did something wrong installing or got bum parts or both.

Got some coolant dye for Dex and circulated it. Pulled the valve covers again and cleaned up the heads so no dye was visible. Pressurized the system and waited. Found a crack in the Castech refurb in the same damned spot as the original head. Very strange. Waiting on response from vendor about warranty replacement. Sucks, but I'm still not in a hurry.

You can see the crack under the blue bubbles.

Do not like. Sounds like the seller is just taking advantage. How do you sell a cracked head as a replacement for a cracked head..?!? Bastards.

That's the kicker. Their site is very specific about using a Sunnen pressure tester to make sure no bad ones go out. I'm kicking myself for not inspecting them super closely before installing....because now I don't know if it was already cracked (presumably) or developed in less than 500 miles (unlikely).

I was finally able to install and set up my Stinger Heigh10 head unit. Once I get the time and motivation to install the amps speakers and build a box for my sub I'll post more updates. Anyone else doing anything for HD audio in their NBS?

Not only that, how can they give you 2 different heads??

They are both 706's...just different casting manufacturers.
