Re: New 7h15 Sanden compressor defective?
You may also have what we call re-heating. Your blend doors may be acting up and allowing heated air from the heater core to over mix into the cooled air. The hot air always wins.

Re: New 7h15 Sanden compressor defective?
"low pressure is around 45 - 50 and the high pressure is around 180 - 200" I assume these readings were taken at idle. Idle pressures have little meaning, as the comp does very little work at idle. No mobile AC does well at idle ie in traffic and stop lites, etc. The set of pressures at 20...

Re: Wiring Question on New A/C Switch
The 2 old switches should be in series with the hot wire to the compressor relay. So, if either were to open, the comp would shut down. So, for one of the switches (it matters not which one), wire the two harness wires together. For the other switch, connect the 2 harness wires to the 2 new switch w...

Re: 53 Packard Patrician factory AC
"Crank pulley OD 6.75", OE idle speed is 450 rpm but I can bump it up to what the compressor would need." Please remember that if you have the idle set too high on a stick shift that you will have a lot of trouble shifting it...you will get a lot of grinding. Try it ahead of time befo...

Re: 53 Packard Patrician factory AC
Which engine do you have? The 288 and 327 were of the same block and had 5 mains. The 356 had 9 mains. Granted this is not a car forum, but I have restored the '54 Packard ambulance w/ 288. Be careful of the rearward valves. Cooling back there was sub optimal and you had to stay on top of adjusting ...

Re: 53 Packard Patrician factory AC
I have discussed this case with some other AC guys, and it is possible that a shop that can rebuild the famous GM A6 might be able to overhaul the OEM comp. (which is a semi-hermetic) Or perhaps a shop that overhauls semi-hermetic comps as used commercially such as a Copeland semi-hermetic. Is there...
