So yesterday I noticed my AC was rather lacking. Thinking it needed charging, I got a bottle of some R134A and a gauge. I filled it as directed, until it was in correct zone for the temp. It worked great last evening. I put maybe 2/3's of a can in. 15oz can.
I go to lunch today and it wasn't super cold, but I wasn't sweating so whatever. It was like 95F out anyways. On the way home, I get nothing. Straight hot air until about 3 miles down the road and I would get cold, warm, cold, warm etc.
I check it today and it's kinda on the low side so I grab a small can. I notice the compressor is short cycling when I pop the hood. I hook the second can up and follow the procedure. I pulled the trigger on the first cycle and right after it purges. Then it purges again.
From there I just watch the gauge. The compressor never cycles long enough to do anything, maybe 2-3 seconds at best. So I unhook it and drive it with the AC on. It purges about 5-6 times, then it finally stops purging. Now its back to the same old, hot air, cold air, hot air, cold air with the random few minutes of just nothing but hot air.
The fans are working, I can visually see the compressor kicking on and off. I'm using the low port, not the high port. No check engine lights. What am I missing?
