My ac had a leak in the fill valve, and over the winter the freon all went away.
I replaced the valve and added freon to it, and the front unit started working well.
When I checked the REAR unit, it was blowing HOT air. Not WARM, but HOT !
Even the condenser coil was hot to the touch.
About that time, the front blower died too.
I replaced that, and the front unit still works well, but I need to know what to check on the rear unit.
