I am going to start with re-charging an otherwise working A/C system.
– It has started to short cycle, meaning you can hear the A/C compressor under the hood clicking on for 3 seconds, and then off for 3 or 4 seconds repeatedly.
– It is not cooling well at all. I have to leave the A/C on full blast for a good 5 minutes on an 80 degree day to get any real cooling in the cabin.
