My A/C seems to be slowing down the hotter the engine and temp outside gets. I got a vent thermoter and it reads 58-60 degrees if it is under 80 dergrees outside over 80 and it does not blow as hard on high, and reads 75-80 degrees coming from the vent. When idling the clutch is still turning but really slow and seems to stick a little. I just converted to 134a, oil charge and stop leak. There is also alot of condensation on the high and low pressure side ? Any suggestions?
