I see the 4 Seasons Parts Rear Eval and Expansion Valve. I have a couple of questions....
The electrical device on the side of the rear expansion valve, is that a solenoid shut off or control flow regulating device? How the fit of the 4seasons Parts?
I have 381K miles and my LC developed engine oil leak, Front O ring around the oil pump and rear O ring behind rear main oil seal retainer plate. I pulled the engine to repair these leaks, decided to replace Alternator, Starter, AC compressor, all the heater hoses, by pass hoses and radiator hoses along with a new radiator while the engine was removed. I changed the front trans converter input seal, cam - crank seals, oil pump, tensioners, t belt and drive belt. I did replace the Condenser removable filter / moister absorbent bag. I evacuated and recharged the system and really hot day the front system would get warm and then get cold, pressures would both rise and both fall together and compressor would not cycle. The rear unit with front unit low blower, would stay steady pressures. 1/4 pound more freon and the system stabilized and stopped having pressures rise and fall when front blower is on hi. I was feeling it was a bad expansion valve in the front at first.
My manual says removal of Dash is required to remove front Evap / Expansion Valve Unit. I purchased a front Evap. Expansion Valve, Rear Eval core, rear Expansion Valve 4 Seasons. I on the fence to send the parts back, or if they are correct parts keep them for when I have to break the system open. So far, it's steady cold when 104 degrees outside, cold front and rear. When I removed the glove box, I see a dash part that crosses the evaporator it's not removable unless I cut it out and adapt it to be bolted back in blocking the removal of the EVAP core. I was able to remove the cover of the evap core to clean the evap core and case.
Has anyone modified this crossing dash part that the glove box attaches too to allow removal of the Evap core without having to remove the dash!
