I have a 2009 toyota avalon. The a/c system has stopped working. The fan usually doesnt run but sometimes it comes on. If I take it off of recirculate cold air comes out the vents when I'm at speed. Today the fan came on but blew hot air. I tried to charge the system today since the fan was running at full speed but the gauge on the refrigerant pegged in the red zone. I dont believe it is overcharged, it acted like the refrigerant couldnt get through the valve and backed up into the hose. the compressor was turning on for about a second and then turning back off repeatedly.
Any ideas what may be wrong?
