Hey everyone, My wife has recently been complaining that the AC will work for a while, but then it stops working after running for about 30 minutes. She also reports that, at that time, the air flow (blower speed?) seems to drop tremendously. I have observed the former but not the latter, so I can't say for sure that if it really drops in air flow or if it's just a matter of perception. I put my AC gauges on it and it reports the following: Static reading is 70/100 PSI Reading system on is 17/145 PSI Ambient temperature is ~92 degrees humidity is 65% Vent reading is ~77 degrees I'm kind of new to reading AC gauges so any tips would be appreciated. I can see movement in the sight glass while the vehicle is running. I'd like to add a little refrigerant (if that's what it looks like it needs) just to see if we can make it through the summer. Prior to the AC problems popping up, my wife and I were discussing trading the 05 in for a new Prius and I don't really want to drop a ton of money into it if we are just going to trade it in. What does it sound like it needs? Thanks in advance!
