W116, New Parts Kits and Manuals

Replaced a/c compressor, evacuated and charged a/c, tested for leaks (found none), replaced a/c belt, replaced receiver dryer, replaced expansion valve, flushed a/c lines. I had cool air (not cold - about 60 degrees at vent) for about three days. Now the air is neither cool nor dry. With the a/c switched on at start up, I hear a squeal. Accelerating eliminates squeal and it doesn't return. Belt is tight. Everything seems to be right but, something isn't and I can't figure it out. Can anyone help me diagnose and fix this?

Hi All: I have some water accumulating in two places, I cannot find the source of either. In the trunk, behind the driver side wheel well. The gaskets on doors and trunk are all new. There is a small seam in the rear window gasket. Also, there is water draining from the car, under the driver side front door. I cannot see anywhere that this could be coming from. Thanks in advance for any help. Jon P.
