AC not working, no leaks, full freon

[reihart]

I recently purchased a 2014 Denali with a rebuilt title that I had to replace the AC condenser due to a common leak issue around the weld that a lot of GM vehicles have problems with. After replacing, it was filled back up with freon and worked well for about 2 months. Now, all of the sudden it stopped working. Checked to see if I had any leaks, none. The compressor still kicks on and off like it's low on freon but I have checked the pressure on it and it's fine. Anybody know what could be the problem?

did you check the pressure with it running a cycling clutch is a sign of low freon

My 2002 chevy silverado runs out of freon in two days and starts blowing warm air. I replaced the ac Line. Dealer part. I see no leaks.  What could it be?

You've got a leak somewhere. Check your high and low fill ports, they are probe to leaking. After that either inject dye to aide in finding the leak or use a sniffer to find the leak. You can also look for oily spots in a pinch. Dye or sniffer is the way to go
