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

Last fall, Mine started leaking down after a few hours. I verified them leaking by airing them up to about 20psi with the Tech2 and spraying soap/water solution on them and seeing the bubbles. I replaced them with the Arnott's. I think they were original, and when I replaced them they had about 115k on them

A year ago they were fine and the bladders would stay aired up and hard over night or when checked after a couple days of not driving.

yep that would be a leak and when you drive it around it leaks even faster, I noticed mine was having a problem because I could feel the difference while driving, it would air up and work fine when started but then go flat while driving turned out the air pump was leaking air out of the relief valve. that was on Arnott pump number #2 rockauto refunded me for it after the 2nd return and I bought the dorman and haven't had any issue, usually the arnott work fine but I guess I just had bad luck the 1st one stopped inflating properly.

it’s always something.

Got out to the dead Hoe today. It wasn’t the door switches, I figured as much.

turning the key I can hear a relay at the fuse panel clicking, but don’t know for sure that means the ignition switch is okay.

I may put a new switch in anyway. The way it’s parked I might have a ***** of a time getting under to attempt a starter.

Just for the hell of it--try swapping the relay? Can't hurt.

Tow it to a better spot.

Finally opened the catchcan..... This was after driving, but still..... It was like soft-serve ice cream..... Contemplating flushing it out to see if something is clogged. Just odd that is has not drained in the past two oil changes.View attachment 271299

Thanks for posting that. I was considering adding a drain valve to the catch can I'm about to install. After seeing that, I'll just stick with unscrewing the can as designed. That crap wouldn't flow through a drain valve!

One at a time, I swapped both the starter relay and crank/run relays. No bueno.
