Air conditioner will blow out cold air if I add freon but within a week it will not blow out cold air on the drivers side. Passenger side has air. I have replaced the compresser and ran dyes and no leaks. It has stumped a few people. Any suggestions?

What are the pressures that your gauges read when you have them hooked up?
It sounds like you have a leak but its either really small or in a place where it is hard to spot.

THIS CAR HAS SEPERATE BLEND DOOR MOTORS FOR THE DRIVER AND PASSENGER. THE DRIVER BLEND DOOR MOTOR MAY BE STICKING OR NOT WORKING AT ALL. THE MOTOR IS LOCATED UNDER THE CENTER OF THE DASH ON THE DRIVERS SIDE. SWITCH FROM COOL TO HOT WHILE FEELING FOR MOVEMENT ON THE MOTOR.

The blend door motors could be the problem. "Raymond" is right.
