The heater does not work in 88 Mercedes-Benz 560sl. The blower motor works but the air coming out is not hot. What should I look at? Motor tempature is OK.

Any details on this are appreciated.
In cars with automatic climate control, the servo unit is always suspect, and especially on Mercedes, which have pretty lame climate control systems, historically speaking. So on the SL, I'd definitely look to the climate control servo, which is supposed to automatically open the various valves and ducts to allow heat into the car. This is, unfortunately, an expensive repair.
Other reasons for no heat include low coolant in the radiator, malfunctioning thermostat, broekn cables on MANUAL climate control systems, and malfunctioning heater valve on manual systems. Maybe others can think of more possibilities, but these come to mind.
I'm not convinced the dealer is right about a plugged system...he'd have to prove it to me by showing me mud coming out of my heater core once he removed it.
