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??

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