I have a 1993 190e 2.6 Sportline with no heat. The car has a new thermostat so this can be ruled out. Does anyone know where I should start or what commonly causes this problem on the 190's?

No heat usually means that there's no coolant (hot fluid) making it to the heater core located in the dash. First, check to see if anyone has "bypassed" the plumbing to the heater core. This is the "poor man's" fix for a leaky heater core or bad heater valve. Then check the condition of the auxillary pump that pushes the coolant to the vavle. If the pump motor died, the flow to the heater core is going to be minimal. Then the expensive stuff . . . the heater core valve under the leaf screen by the windshield, or the heater core/vaccum valves (which require dash removal for inspection.
