rear ac delete
get almost no cold air out the front which leads me to think that the rear expansion valve is toast.
The piping doesn't run in series does it? I mean isn't he proceeding from an erroneous assumption that blockage in the rear valve is cutting flow to the front. I'm just trying to understand the system.
I had a malf. in the rear-- no "click"; it must have been electrical, I cleaned connections, solenoid clicks, air is cool.
Even if it is working, there may be a leak in the rest of the system, causing it not to work, I found out the hard way.
Best way to check the heater valve is to zip tie it closed, and see if it makes a difference to the cooling. Mine is permanently zip tied closed, who needs hot air in dubai anyway?
