Re: My turn, need the wizards
Is there air flow coming out of the vents? Is the evap freezing up? Put a monentary switch in the clutch circuit and manually cycle the clutch. Will the vent temps return to normal? Evap could be plugged.

Re: 1988 Chevy Suburban r12-r134a retrofit problems
I do not use Four Seasons anything. Their compressors did not hold up and that was enough for me. I do not even try their evaps or condensers. Did this vehicle at one time have a dual evap system?

Do not use superheat or subcooling in MVAC. The compressor speed changes and superheat will also change. Throw those readings out the door. These readings are used in stationary refrigeration because the compressor speed is constant. Get a new belt on there and check the idler and pulleys. Also, dis...
