The drain could be plugged from your HVAC unit allowing too much moisture to build up, the A/C side of the system may not be operating in the modes it is suppose too, that dries the air during winter months. Could also be a blend door servo not functioning. Try an independent shop, tell them exactly what is happening, as this system is computer controlled it could be a number of things. They will know how to pull the system codes and diagnosis it.
