92 300TE A/C Not cool enough
1992 Mercedes 300TE
Recently, the A/C compressor started leaking freon. I
bought a new compressor and had it installed by a
qualified mechanic. Now, I am only getting around 60
degrees vent temperature. The compressor checks out
good, ie, low side pressure at 1200 RPM is 28-36 PSI. High
side pressure is 225 PSI. The mechanic says the expansion
valve is functioning properly.
Before the compressor was replaced, the vent temperature
was around 45-50 degrees. (The system has been converted
to 134 several years ago) He did NOT replace the dryer -
he said there was no need to.
He doesn't seem to know what's going on and, of course,
neither do I.
Please help.
