Heater won't work

(1990 Mercedes-Benz 300SL)
in Fallbrook, CA on January 03, 2010
this car is actually a 1984 380SL . It only blows cold air and no warm or hot air at all, even in the heat position. I wonder if the diverter door is stuck.....or..... any help out there? Just purchased this vehicle and ordered the Owner's Manual.

I would check the radiator hoses to make sure that they are really hot, if not, it is most likely your thermostat.
