It’s very easy for a system to hold vacuum indefinitely, but immediately leak when it sees positive pressure.

You can fill the system with nitrogen and listen for leaks. You could also charge with some UV dye.

The condenser is the primary filter on the system. When a compressor fails & sheds pieces, they go straight to the condenser. Parallel flow condensers have tiny passages - in parallel. When the trash blocks one passage, you lose cooling capacity. They are hard to block completely, and are nearl...

Thank you for the reply. Unfortunately, I have no back story on this car other than that 'it has a new compressor', which we’re not even sure if that is true. However, condenser appears original so I doubt it was replaced. Also since it was a used car lot, I'm highly doubting they replaced anything ...

A friend of mine just bought an 06 Civic 4 door from a Buy-Here-Pay-Here lot and the AC is not cooling as it should. Lowest vent temps we can get are 58-62F and it just never cools down. Evacuated, vacuumed, and recharged the system by weight and here are my results. Ambient temp: 83F Vent temp: 60F...

Just an update, it was a bad compressor. This style compressor without a clutch has voids that break away if the compressor seizes. So, the pulley was able to move freely but internally the compressor was seized.

New compressor, TXV, condenser, and cleaned lines and it’s blowing nice and cold.

Upon further research, it looks like I may be dealing with a failed variable displacement solenoid.

Hello all, I am working on a 2007 Toyota Camry 2.4L with inoperable AC. Here's the details ~85-90F outside, high and low side pressures both the exact same at about 145psi. I have 13v going to the compressor with the AC on, and I have verified 0 ohms resistance from ground wire connector to engine g...

Hot water shut off valve may be leaking. Hi Tim, thanks for the reply. I will check into this next time I am near the truck. Based off of the pressure readings, is there a way to tell what the vent temperature should be close to? Also, the only things I'm not really confident about with this AC pro...

1993 Toyota pickup truck, 22RE. I’ve installed a whole new AC system into this truck including new: condenser, evaporator, TXV, receiver drier, compressor, etc, and flushed all lines. Installed all new parts with pag46 oil. So, I had been having performance issues with this truck last summer after a...
