my air conditioning only works when I’m driving forward, and does not work at all any more when I’m sitting still at an idle. this is a new problem. the A/C has worked like a champ for the past year (since I started using this vehicle). I even refilled it by myself last summer, with no issues until now.

when it is at idle, I hear a clicking coming from the A/C system, and the RPM’s arch a little bit. then it clicks again, and the RPM’s go back down. it does this 2-3 times a minute. also when at idle, the air is VERY HOT, considerably warmer than the outside air.

also, I have a pressure gauge for the A/C system (came with the refill kit last summer) and it says that the system is holding too much pressure. it suggests a possible mechanical problem.

1 - what are the possible problems?

2 - is this a DIY fix?

thank you, everyone!
