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

[Dantheman1540]

I didn't get the Belltech kit, just a stock setup.

The caster may or may not be out of spec then, I guess they will tell you when you go back. Sucks I didn't know about the kit till after I paid for an alignment but I don't think it was out of spec with the keys de-cranked only when I did coilovers do I think it did.

I'm taking it back to the same place that did it before, so who knows--unless a different non moron will look at it this time.

Got home Friday night and the front blower motor was running full blast, wouldn't change with the fan control and stayed on even with the ignition off. So ordered a new fan control module and Amazon was helpful and delivered it a day early, so I was able to get it fixed before going back to work today.

I have the automatic climate control which uses PWM to control fan speed instead of resistors. Apparently, the power MOSFET decided it would rather be a diode. I'll probably tear it apart and replace the MOSFET and keep it for a spare, since the reviews seem to indicate that the aftermarket ones don't have a very good track record.

After a pretty thorough underhood cleaning I had a p0332 show up. I'm probably due for knock sensors at 200k+ miles anyhow...

Any tips/tricks or while your in theres? I've got an oil pressure sensor to put in already

Valley cover gasket and oil pressure sensor. Make sure to do an RTV dam around the knock sensors like suggested and replace the knock sensor harness while you’re at it.

Should I plan to replace intake manifold gaskets?

I'd say no, they are very nicely made and I've never replaced any LS intake gaskets, not even on my super charger setup.

Dammit. Thanks for looking, and for the part number.

I would. But that’s me. Others like Dan say no. They’re fairly cheap. But then I have battled an intake leak with my Whipple manifold and that SC is not easy to R&R.

I agree, blowers blow

You can always have then on hand, and if the old ones look great and you don’t use the new ones, Amazon has a great return policy. I just always replace stuff like that on a job that’s difficult. I don’t like doing things twice.

Turned on the ac today and it's not working, but the little ac light is on steady like it is--it's not blinking. I don't hear or feel the clutch engaging. Any ideas? I'd think if the ac tensioner seized up I'd hear or feel it, that happened once before. The compressor was replaced once before with new--thx to @mountie .

My A/C quit working a couple years back and turns out the guy who replaced my power steering pump a month or two earlier didn't take great care when he reinstalled the wire loom bracket (on the back side of the reservoir), resulting in the bracket cutting through a wire loom and grounding out a wire in the bundle. It kept blowing the 10A fuse in the fuse box under the hood.

Once I found the problem, I removed the bracket, fixed the wire loom, and reinstalled it correctly.

Not sure if this is what's causing your issue, but thought I'd throw it out there.

Not sure yet. Gonna bring it to the guy next week. I'll def update whatever he finds.

My AC just stopped working again....... Compressor turns on then right back off. Guess I'll check pressures when I get home. Round 4 I think of AC trouble, getting kinda old.

I hate AC trouble. Kind of a PIA to figure it out when it quits.

Very nice! I did the fronts, but not the second row. How hard was that part?
