Has the compressor been replaced recently, and was it a brand-new unit? If so, what else was done at the same time, if anything?

I believe your car has a variable-displacement compressor. If so, you could try replacing only the compressor's control valve first. But with that amount of mileage on the car, I too would go ahead and replace the entire compressor/clutch assembly. I strongly recommend replacing both the condenser a...

After one hour, the HP and LP sides should equalize. If they don't, the cause is usually a defective metering device—in this instance, the TXV—and/or a blockage someplace. Presuming a full charge of refrigerant, if you're seeing only 100 PSI on the high side at an ambient temperature of 76°F, it doe...

Bill, if your password was a simple one, whomever did the hacking probably just got lucky, guessed it correctly, and logged right in. It's a good thing that you changed it right away because I'm sure your original PW has already made it onto the Dark Web and is now for sale, even though it's no good...

A few additional thoughts... You should hear a click when the clutch engages and then a running-compressor noise, which should be fairly low in volume and constant whenever the clutch is driving the compressor. If it's much louder than that—like the sound a steel-wheel roller skate would make whose ...

Other problems could be in play here, but yes, the clutch air gap might have become larger since the car was new. The largest the air gap would be is when the engine is cold, or in the morning on first start-up. It's not large enough to where the clutch will no longer engage, but it is to the point ...

Yes, I did. Does that mean someone hacked your Forum avatar and login?

Appreciate your following up and sharing what you did to correct the problem.

I had a similar issue with my Kubota B2601. It sounds like there could be a problem with the expansion valve or maybe a refrigerant flow issue. In my case, it turned out to be a malfunctioning expansion valve that wasn't regulating the refrigerant flow properly, causing abnormal pressure readings. ...

If the system is only half full of refrigerant, ~8 ounces net weight, the binary or trinary switch (the switch with the three wires connected to it) has probably opened because of low pressure. It's actually doing its job and not allowing the compressor to run under such conditions. Before delving i...
