heater system valve -85 300CD

It's mighty cold in the old Benze...when I turn the heater control up to red "max", I get a puff of warm air, then nothing (much)is circulating in the heater core. How can I trouble-shoot the valve that opens/closes to allow the warm water to circulate?

My initial thought was to try a hammer, but I decided to check this group first.
