Is there a way to test the climate control unit to verify that it is working properly?

I assume the dial on the ACC regulates how much the mono valves opens.

Any idea how to measure the current at the mono valve?

I think mine if fried because my ac is blowing hot and I don't think the mono valve is working properly. I took the mono valve apart but there are no tears in the rubber diaphragm.

I'm going to install the 1amp fuse tip on the aux water pump.

I was thinking about clamping the water hose going to the heater core.
Has anyone done this?

Thx

Pete
