Automotive Air Conditioning Information Forum

A few questions, if I may:
Did the system hold a vacuum for at least a few minutes? Did you attempt to re-charge it with the A/C system and possibly the engine switched off? And how did you re-charge it, by weight or pressures? What was the original reason for the re-charge?

It could be residual oil and maybe UV dye that you smell because as Tim said, refrigerant by itself is odorless.

My "sniffer," an older pro model, goes through a self-diagnostic routine and sounds off when it's first switched on to let the operator know that it's working and the sensor is intact ...

You should be able to find the correct HPRV at your local Ford dealer. Bring the old one with you, if possible, along with the engine specs and compressor maker, so that they can match it for you. If memory serves, I believe 3 or 4 different V6 engines were offered for the 2003 Taurus. I'm unsure ...

On that subject, it looks like I’m going to have to make a 134a TXV work. It’ll feed the evap R12 just fine, the only problem is that it physically doesn’t fit. I don’t have the parts in front of me but if i remember right the 134a TXV had a smaller threaded end on the suction side.
Is there any ...

Besides the last statement, what did I do incorrectly here, and why is it venting with what should be the correct weight of charge?
The pressures are reasonable at idle, but I would re-check pressures at about 1,800-2,000 RPM to determine whether the high-pressure side is actually too high ...

So would my next best move be to check impedance at the clutch and go from there?
If a compressor is needed do I have to stay with an OEM Denso or are their other options
The dealer said that the compressor was failing internally. Based on their statement, the compressor assembly needs to be ...

Sounds good. I wonder whether you can find the missing part—if not at a Chevy dealer, maybe at a local salvage yard.

Based on the data you posted earlier—ambient temperature of 85°F and 1,500 RPM, the pressures of 25/180 PSI still seem a bit low to me. The low side should be ~30 PSI, and the high ...

I have a 2020 Jetta with no functioning Ac.
I had difficulty finding a shop to service the 1234yh refrigerant so I ended up at the dealer.
The quote was 4500 dollars Canadian.
Well i guess I am rolling the windows down.
Not surprised about the difficulty finding a shop that could handle R-1234yf ...

I bought a 74 F100 with a later model engine using a FS10 compressor, TXV, & parallel flow condenser of original size. The previous owner never tried making AC work. The compressor & condenser & evaporator were on the truck & they dont look new, but they were capped off. I removed compressor ...

Please allow me to put your mind at ease.
