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

probably should have turned off traction control first, it kicked in about 1/2 way thru

Good way to powerwash under there. I do the same.

I’d leave the ac belt off if you suspect the compressor is going out otherwise you might end up with metal shrapnel throughout the system like I did. I ended up replacing almost everything due to that- it even made it all the way to the rear evaporator core and when I tried to flush that, I couldn’t because there’s an expansion valve that you can’t open manually so you need to remove the rear unit and open it up. Unfortunately in order to do that you need to remove the rear lines and they’re connected under the vehicle where they corrode themselves in place so I had to buy a complete flexible rear line set for about $300 plus then I figured just replace the damn evaporator and valve…all told it was over $600 -700 in parts.

Excellent advice, thank you. That’s exactly what I will do.

What's your engine hours. We are doing a study.

400,000 Mile Club

8277.5 hours at 408,512 miles Interesting! So your average is 2069 hours per 100K. So maybe my hours are correct? I am showing 5052 hours at 345,000K, that would make my average 1443 hours per 100K. @Geoffsfas10 is showing 3800 hrs @ 103K. So Mine seems low, his seems high, and you are in...
