No AC on my 2006 yukon xl

[2006-yukon-xl]

Hi All,

I first noticed a week ago the a/c wasn't blowing that cold. Now I get nothing, but hot air in both, front and rear. I thought maybe low freon and tried to charge but the system didn't take any because the low pressure side was good.
The clutch does kick on and off. Also, the accumulator doesn't form any condensation. Any suggestions would be greatly appreciated.

What do you mean the low pressure side was good?

The system is not isolated inside........ between high and low. Its the restriction that causes a change in pressure

The gauge that's on the freon can indicated it. Don't own a set of manifolds to check.

The stuff from Autozone is crap.

Get some real gauges. If you don't know how a ac system works...... please get a real tech to look at it.

It will be cheaper in the long run.

Not trying to be a *****.
