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

Does anyone have a probe thermometer and can check the ac temperature coming out of the vent when cranked down to 60, im trying to see if need a ac service or if I'm crazy but seems like it should be about 34/35 in the vent slot mine will only go down to 46

lol, maybe you need a recharge too, the temps here are only hitting the high 80's so far and It just seems like it is not working as well as it did last summer when it was much hotter, I checked my silverado and it goes down to 36 and I just turned it on for a few minutes the yukon had been going for a while already

Honestly this is not a good way to measure the performance of ur A/C. To many variables for anyone giving you there trucks performance. A good way to gauge is if the temps coming out is at least 20 degrees below ambient temps.


If you need it charged find a good mechanic that uses gauges and temp to ensure correct pressures

If you need it charged, you have a leak.

ya I know a shop that has a machine that takes out everything and puts it back in by computer, they did the silverado for me and it kicks butt

03, I don't know which it has I would imagine the 134, shop did that one for me 2 years ago at least
