[QUOTE="Greg Gibbs, post: 1034426, member: 59598"] I'm having an A/C issue with my 2002 Explorer Sport Trac 4x2 with 153K miles. I've read lots of posts about A/C issue, but nothing quite like my symptoms. My A/C works normally most of the time, but will occasionally blow warm air when I'm in stop-and-go traffic or after idling for a few minutes. When I get back up to speed, it seems to operate normally. I had similar symptoms a couple years ago and a local shop added some refrigerant, which helped. This time, I bought a can of A/C Pro with the gauge with plans to add refrigerant myself. According to the can's gauge, it was within tolerance, but on the lower side. I added a little refrigerant (not very much), but it did not fix the problem. The engine has never overheated and the engine temp gauge doesn't indicate any issues (stays left of center between C and H at operating temp). I've also replaced the fan clutch and water pump recently, along with the radiator cap. While troubleshooting today, I noticed that the A/C compressor clutch is ALWAYS engaged when the A/C is on. (Most people have the opposite problem.) I'm accustomed to it cycling on and off with a loud clicking noise, but it currently doesn't turn off unless I turn the A/C to the off setting. (It also turned off when I pulled the A/C compressor relay as a test.) Since it was cheap, I installed a new A/C clutch cycle switch ($13) on the accumulator, but nothing changed. I'm guessing the answer is to have it serviced by an A/C shop, but I'd like to know what could be causing this. Compressor clutch/coil? Expansion valve/orifice tube? Any other ideas? Thanks guys!
