[QUOTE="Greg Gibbs, post: 1034429, member: 59598"] Even in summer, I thought the compressor should cycle on/off every few seconds. I can't recall it ever running constantly and never cycling off. Also, the tube from the accumulator to the compressor has condensation on it and creates a pool of water under the truck. I've never noticed that before. It usually drips only from the evap tube area. Regarding that clutch cycle switch, I assumed (after a quick Google search) that it would have a Schrader valve to prevent loss of refrigerant during removal/replacement. I was surprised when it started hissing (leaking) when I took it off, so I just replaced the O-ring and put the new switch on as fast as I could. Afterwards, I checked the low-side pressure with the gauge on the can of A/C Pro and it still indicated that the pressure was good. (I realize opening the system is not good.) Assuming the compressor clutch should remain engaged all the time, any other ideas as to why my A/C blows warm air after idling? [/QUOTE]
