1987 Chevy R30, converted to r134. All new A/C components except evaporator. In morning will cool vent to about 52 degrees, pressures 35/220, but as the day warms up temp at vent gets hotter to about 80 degrees and the pressures rise to about 60/300. Put fan on it and pressures will drop a little bit and vent temp will go down to about 75 degrees. Also, as vehicle warms up the temp and pressures go up a little bit.
