Hi all my problem is before i did'nt have no heat and then I bought and had my mechanic install a monovalve and now I too much heat in that I can not turn it down with my auto climate control dial on the dash.When I told the mechanic about this he said this is a common problem with these vehicles and that something in the control has to be re soldered.Did any one else have this probl;em and is it an easy fix as I am out of a job right now and am trying to save where ever I can.
