Scotty,
I have a 2000 Toyota Echo, 172k, A/C at idle crepes up from about 48 to 62⁰ at vent, replaced Compressor, Condensor, Expansion valve, and no real help, had professional evac and pressures look good, I can only assume oil to freon ratio correct..Increase RPMs in park will bring down the temp coming from vents after about 1 min at high idle, and my mastercool digital gauges shows my freon liquid temp goes from low side 45-25⁰, condenser fan works good and increases as to engine, any help would be appreciated..Thx
Mitchell
Does the vent temperature come down as you drive it? The more air passing across the condenser will help the system run efficiently. Is the aux cooling fan running smoothly? Air flow is necessary as is proper flow within the system to obtain proper output. Eliminate possible flow issues one at a time. Air flow through the condenser. Refrigerant flow through the hoses and pipes. an infrared thermometer can help monitor temps on the condenser, hoses, and pipes.
I hope you find this helpful.
