2007 Yukon Denali XL A/C cutting out int

[Rayaz_XL]

The vehicle has 163,000km on it. The problem is the A/C is not as cold as it was. More so when I am driving, i notice all of a sudden warm outside air being blown through the vents instead if A/C. Intermittently, the A/C kicks in but very moderatly, even though the temp is set down all the way, and it is not on AUTO. Even on recirc mode the A/C is not as cold as should be, and cuts on and off especially when driving.


Any comments, advice, opinions, experiences, etc appreciated. Thank you.

Probably just needs a gas recharge since it is over 100,000 miles.

What I did was basically a cheap temporary fix, because i have two babies under the age of two in the vehicle that should be cool and comfortable. I tried out a product called Duracool. It states it works best if you have 35-40% R-134a in the system. My system was around 40-50% full. I topped up the system with the Duracool product and it is Ice cold! On a very humid day there is frost blowing out of the vents occasionaly when set all the way LOW.
