A/C Help

[markho]

Hi, the air in my car stopped working a few months back its a r134a system. I recharged it in early spring and it worked good enough about 2 months.

I checked for leaks and didn't find any. It blows ambient or a bit more than ambient air. I have replaced the monovalve so far.

The compressor is engaging when I turn the A/C on, and I can see r134a flowing through the system at the sight glass. Whether or not there are bubbles I can't tell. Please help its hot!
