I have not resoldered the CCU. The compressor works. With the temp dial set on MIN the system blows pretty cold. The minute I rotate the wheel, the center vents close and the system starts blowing really warm air. My aux water pump failed a while back and I just removed it and placed a short piece of metal tubing in the space.
