A/C low side pressure to Hi
I recently purchased an 86 300E with 109,000 on the clock. A/C compressor was bad, so I changed it out and also replaced the expansion valve, accum/dryer, pressure switch and fan switch. New valves to convert to 134r. All went perfectly for about 3 months.
In the last three weeks, the A/C wasn't blowing very cool. I checked the system and have about 90 - 110 lb.s of pressure on the low side. I believe normal should be 30 - 40 lbs. I have flushed the condenser, evaporator, replaced both the expansion valve and accum/dryer.
Still holding hi pressure on the low side.
Any ideas or solutions? What am I missing?
