A year ago my a/c starting blowing just slightly cool air. I figured ok, the car is 6 years old, time for a 134a top up. Bought a kit in the states, with gauge, and emptied most of a 134a can into the system.
When that did not fix the problem, I brought it to a shop. Pressure test, dye, can of 134a, and I was on my way. they did not find any leaks btw...
Since my A/C was still not cold, I figured I'd empty what was left of my 134a can. On max a/c, with the can attached and dumping, it shows 22 psi (too low) when the compressor engages, and 45 psi (a bit high) when it disengages. It would seem to me the frequent cycling I experience is due to a lack of 134a refrigerant (low pressure switch disables compressor). Does this make sense? Any body else experience incessant cycling and lack luster performance? I do not want to wreck anything, but the gauge shows the pressure to be on the low side, at least when the compresor engages...)
Time for another can?
