i have a 1987 E300D and the heating has not been working properly. the fan needs replacing or i need to check the fuses? it is w/o the fan, when i depress the defroster button it does send hot air up to the dash after warm up and i could live with it if i could just get the internal flappers to send the heat down to the feet.
when i depress any of the other heater buttons the heat is not sent down to the feet or the center dash area...just the defroster gets the hot air.

i remember that there are some relays that control the flappers behind the glove box somewhere? this correct?

also is there any way to manually direct the heat down to the floor or at least to the defroster and the floor conbined w/o investigating relays?
