Question about 1992 Mercedes-Benz Mercedes Benz 300 Class
Have you pulled the heater core to see if its getting enough flow. If its filled with old nasty built up congealed coolant then it will not work. I would pull it, see if its nasty inside. put a hose to it and see how the flow is. If its clogged down at the bottum of course this won't really tell you anything. Check to see if your fan is working. If air flow is not getting to the heater core then you wont get any heat either.
