Re: A/C Troubleshooting Situation

Dead scroll compressor. It is shedding debris in to the condenser. Probably low on charge, but it is done. You can add a few ounces of refrigerant & re-test, but I suspect you will see the pressures remain the same. The condenser is the primary system filter. Since it is 7+ years old I would rep...

Re: 2012 Ford Escape AC Troubleshoot

Did you pull a vacuum after you put the system back together?

How much oil did you add to the system?

Re: Help with new AC system 1984 El Camino

What port did you charge the refrigerant through?

Did you charge as a liquid or a gas?

The oil charge will not block the orifice tube.

How does the compressor feel when you turn it by hand now?

Re: AC makes a vibrating horn sound while car is idling

On your 1987 Corolla FX16 with dealer installed A/C it is possible to put the dryer in backwards.

Re: 134a back to R12?

If the VIR was not serviced, the system was not flushed. It is not possible to flush through a VIR The desiccant bag in the VIR is part of the service - so if the VIR looks "untouched" - it has a 40+ year old desiccant bag that is not 134a compatible inside of it... The system also still h...

Re: 134a back to R12?

That will depend on how it was converted.

Which oil was used in the conversion?

Other than the compressor, is the balance of the system the original design?

Re: R134a price up over 500%

As Hecat just documented above, they want to run 134a out of existence. They can't run it out of existence when it is still so commonplace though. There are plenty of vehicles which are only a few years old using it and what are we supposed to use when the condenser fails and needs replacing? It fe...

Re: A/C request signal

Much of the PCM / ECM / BCM world operates at 5 volts & milliamps of current. Jumpers & test lights can damage the computer. If you have the Factory Service Manual, the entire troubleshooting flow chart & circuit diagram is present. With that in hand, you can fix it. For $19.95 you can b...

Re: 73 stingray with high AC pressure

Converting a Corvette to 134a is a fools errand.

R12 is still available. Some cars just need to stay that way, and the Corvette is the best example.
