Question about 1996 Mercedes-Benz E-Class
Heater fan motor and fuse proved to be ok. can't find a Siemens component 539.9879.770 (4 x 30cm red,black, blue, yellow cables to a RESISTOR)
Heater motor is prone to water damage when the small drain scuttle drain gets blocked (usually by leaves).
If the passenger footwell carpet is damp, that's probably the problem.
Worth checking regularly anyway, and/or remove the small cover over the drain which is part of the problem.
Remove the heater assembly (located over passenger footwell) and replace is the easy answer.
It is possible, depending on ability, to strip and repair.
New from Europarts around £130, used around £60.

SOURCE: location of blower motor fuse
Fuse blower motor is not in the fuse box. It is located outside. lOpen the hood, on the driver side near the fender, about 1 feet from the fuse box toward the direction of the radiator, there is a retangular about 1x2 in with wire coming out from each end. Snap it open, inside is the the wire fuse.

Common problem with the E-class and the blower motor not working was the blower motor regulator. It is mounting right to the blower motor cover on the passenger side underneath the dash. Pull the under dash panel off and you will be able to access the blower motor cover. Pull off the cover to expose the blower motor and the blower motor regulator. Most of the time it is the regulator that goes bad but is possible the blower motor may be bad instead or also.
