If it still had pressure when it quit, it may have been something as simple as an excessive clutch gap. Any chance you can get an electronic leak detector? If so charge a few ounces & go looking for a leak. The suction line nut on the compressor could be loose, I have seen it before. Try it with...

Fixed Displacement compressors with a TXV may cycle. If the heat load exceeds the capacity of the system the compressor stays running. The only reason for the compressor to cycle off is to prevent ice formation on the evaporator. Around here at 115f & 7% RH I can let an evaporator get to 20f wit...

The 2012 Corvette is equipped with a CVC compressor, a variable displacement unit. It does not cycle, it just reduces displacement to maintain a pre set low side pressure. Are you keeping the 2012 Corvette PCM? Since the compressor is designed to perform the same function as the POA, I can only gues...

A wheel type pipe cutter will pop that dryer can in half with no fuss if you want to see what went wrong with the old one. Cut the bottom 2 inches off for fun...

When you can't actually change the fan speed on it, the blower speed module is done. It gave you a couple of warnings, now it is failed completely.

The auto climate units use a solid state control instead of a resistor, but it is located in the same place.

Mopar has a long history of fan speed ratio changes with the LA engine. Any mopar forum is full of folks that are clueless about when, why & how it works. Non A/C 318's started with cooling fans running at pretty much 1:1 with the crankshaft. A/C cars had a 1.5:1 OVERDRIVE on the water pump &...

The operating envelope of MVAC is huge compared to stationary stuff. That is one reason we never talk about superheat. The airflow & heat load on the evaporator vs the airflow & ambient temperature for the condenser, and the compressor capacity - think about an EFI map with all of that on it...

If you are going to work on it yourself, you need a proper Gauge Set: http://www.ackits.com/mt1416-santech-r134a-brass-manifold-gauge-set-w-72quot-hoses-24615 You can't just "evacuate the extra pressure" while guessing at things with a can & a plastic low side gauge. If you indeed did ...

Looks like the TXV is doing it's job. And you are slightly undercharged. With the cabin fan on the highest speed, and the doors open the high side should climb some. The TXV is trying to maintain a 40f discharge line by modulating the flow. At idle there is not enough compressor volume to pump down ...

Block valves sense temperature directly from the suction line, so insulating it will have no effect. The adjustment will be under the cover on the end opposite the sensing diaphragm. In theory they are all adjustable valves, but some are easier than others to access. What sort of evaporator design i...
