My air conditioner had stopped working all of a sudden. I tried to add R134A refrigerant but the gauge was showing it was full. At first I was thinking I may need a new AC compressor. But before that I decided to do a few basic checks.
First I checked the sub-harness where you plug-in the compressor and alternator. I noticed the alternator pigtail was in very bad shape. I replaced the harness with a used OEM one and then I went to check the AC fuse. To my surprise it was blown. Soon as I replaced it, the AC compressor kicked right on.
The R134A refrigerant gauge now read low but a good sign since it just needed more. I refilled it with a full can of R134A refrigerant and now the AC is ice cold, super ice cold. I suspect it was the bad alternator pigtail that probably caused two wires to trough. This is what likely caused the 7.5 amp fuse to blow.
Now back to cruising with a nice COLD AC in this summer weather.
