Cold in my 1999 E320 4matic

Hi there. I can't find a forum for my vehicle, so I post here.
The central vent "doors" that allow heat or cold air to blown by the fan into the cabin will not open in "heating mode." They work normally in "cooling mode." It seems there must be a thermostat or a relay that's not working, and I wonder how to go about diagnosing and repairing this.
Thank you.
Please reply.
