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?

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.
