Question about 1998 Mercedes-Benz C-Class

1 Answer

C-180 Blowerfan has a mind of its own

Heating fan does not turn itself on.
After abt 15min driving and if switch is put on, blowerfan suddenly awakes. No probs with heat.
Suspect either fan engine replacement or resistor replacemant or
relay ? replacement.
Appreciate any advice on this.
Suspect repair must go in via front middle panel.

Since you have electricity, and therefore the resistor is functioning...
Take out the rights side facia under the dashboard. (loosen 3 screws)
Push the two white clips apart to opn the fan box.
Open the box and check for dust and other particles, vacuum, and clean out the engine,
oil w-40 it (axle) a bit, Open the filter box shich perhaps have never been
changes, and then tap the fan engine with a small screw driver
and voila if you are lucky it will come to a rude awakeing...

Often the contacts and the engine just needs overhaul, ie TLC....

WITH THE POWER OFF take one out of another spot just long enough to check it,The best way is have a hand full of different ones. Plug & play. If you use one that is exactually like your possible bad one, plug it in. On the relay you can see a Schematic diagram and compare the two.

Well lets see the fans wint turn on the car


Change your termostat in the coolant system also check the fan motor itself if the motor runs while the air is on the car is bypassing the tempiture sensor relay that turns the fan on when the engine hits around 180-220 deg. it will turn the fan motor on and then back off once it hits around 160-170. so I would say most likly its your relay that is bad and you should change out the thermostat just to be on the safe side with the over heating problem as well...

My autoheadlight system and blowerfan wont come on


Certain circuits go through the ignition switch and sometimes the points in the switch become gummed up with carbon. The easiest fix is to replace the ignition switch. The switch can, however, be disassembled and cleaned by a skilled mechanic (there are many small springs and parts that have to be assembled properly).

Long story short, replace the ignition switch.
