Climate control works. Mechanic replaced the following

monovalve "saw water in the coils"
evaporator temp sensor(near accelerator) "circuit was open"
pushbutton unit -did not open doors and poor temp response
aux coolant pump apparently ran but current draw gradually increase to 10 while he was measuring. When we took apart the pump the bearings turned but not smoothly. The bearings had a notchy feel.

Amen. When the system works I do not notice it.
