Flushed all of the components. Used the Four Seasons AC flush from NAPA. That stuff is pretty potent, flashes off quick and clean as well. Put a quart through the evaporator, almost 2 through the condenser (removed and sloshed around). Drained and refilled the compressor and pumped it while draining. Replaced the accummulator/drier and orifice tube along with both high and low fittings. Remembered to take the old schrader valves out of the r12 fittings before attaching the adapters this time.
Used an orange orifice tube because that is what they had at the store when the previous one came out black and scongey
When I was flushing the heat exchangers the flush came out black at first and there was black in the old orifice tube. I flushed until they came out clean and blew them through with compressed air, same process for the hoses, the discharge hose from the compressor was new and had not been contaminated even though it was already installed. Replaced the low pressure switch with one for r-134a as well, then charged with 7-8oz ester oil and charged to appropriate pressures with r-134a.
AC blows nice and cold, now if I can sort out some of these vacuum leaks the ATC would work properly as well.
