A/C pressure to high, Need Help
I recently purchased an 86 300E. About a day later, the A/C compressor went south. I changed out the compressor, accum/dryer, expansion valve, pressure switch and fan switch, related valves to convert to 134R. Everything worked perfectly until a few weeks ago.
Thinking the system was low on coolant, I put gauges on and discovered the low side pressure was in the range of 90 - 110. Knowing it should be 30-40#'s, I flushed the evaporator and condenser, replaced the accum/dryer and expansion valve again.
Still holding the high pressure on the low side. Anyone out there that has suggestions/advice, please speak up. It's mighty warm outside.
