A/C BI-POLAR

1987 Mercedes Benz 300dt • 185,325 miles

This is a new to me used car. The a/c has been charged, condenser works, belts fine. The a/c blows cold, the after a little bit starts blowing warm with no change in air blower pressure. If you turn the car off, when you turn it back on it blows a/c cold again for a while. Time for blowing cold varies. Any thoughts as to what to look at next? Any help would be appreciated.

Could be air and moisture in the system forming into ice and blocking off the orifice tube-have it evacuated -start here
