Earlier this month I have discovered my truck having a clicking noise when the key was in or our the ignition or even if I was in the car or not, that stopped after a few days. Well recently My AC has started blowing Hot after a few minutes idling in a parking lot. I put a set of guages on the HVAC system and I have a video of it and it appears that when I am at 200 RPM the High side pressure is getting well over 350PSI and this all of a sudden happened I went on a 900 mile trip last month in it and no problems what so ever. Then I heard a clicking noise, then I noticed heat coming out my AC.
Any other information you need let me know, as I put this in the 911 section because this is urgent being I am leaving for a job on friday.
It also appears that my fan clutch is working and I have no trash in front of my radiator or condenser.
