Ok,
The valve definitely has power, just a tad over 12v. And the hoses are warm to the touch. So from Pete's post it's the monovalve.
The expansion valve is ice cold with condensate on the line going to the evaporator coil.
There are 3 hoses going into the firewall 2 from the valve and one from the engine block/pump. The 2 from the valve are warm. The one from the block/pump is HOT!!. Is it normal fror it to be that hot?
There are also 2 more hoses going to some kind of defrost unit for the wipers??. Both are HOT. Do I need to worry about them. One of these lines is going into the bottom of the valve.
I wish I had a diagram of the water flow circuit.

Also i put power to the auxiliary fan directly from the battery and it didn't work. So I need to replace the motor.
