After getting the Sequoia started, the primary objective being to get some air in the bags to raise the rump, I was fiddling with the heater/ac controls while the compressor and the bags did their thing.
No fan at any settings. And no AC compressor action when the dash control is on "A/C".
Looking at the wiring diagram to figure out what to trace, I figured the AC compressor cut-off switch might be keeping the compressor from coming on (probably low of freon). To figure out where it is located, I looked at the MM. And I read what the MM says:| Quote: |
The compressor should not run below 25°F. ambient or 37 psi at the switch. The compressor should run in A/C modes above 45°F. ambient or 42 psi at the switch.

That leads me to believe the pressure switch is looking for something over 37PSI.
Emery Stora once posted that, at 1500 RPM and 80F, the low pressure side when running Duracool would be about 20PSI.
Does everyone charged with Duracool bypass the low pressure switch or what?
