Fan /blower in my Mercedes S280 1998 model not working no noises Just wont blow. All switch lights related to A/C ventilation are ok.

have the fan control module check as it has probably failed

Yes,could be your blower resistor is bad,it's right next to the blower motor,it controls the blower motor speed,easy to replace. Duralast Blower Motor Resistor Just took a guess at the model type since you didn't state,wow,high dollar price,guess it comes with a Mercedes,paid about 18 bucks for mine on my 85 Nissan.

Ok i could be 1 of 3 things blower relay,blower switch or blower motor resistor.First thing to do is check the blower motor resistor by pulling on and wiggling the pigtail to the resistor with the ignition and fan switches on.Then if there is no bad connection i would replace the relay and if no change afterwards replace the fan switch.

Blower motor is bad or resistor that governs motor speed.

Horn and heater may be fuse related. The headrests have nothing to do with fuses. The switch is bad or going that way for the seat or the motors for the headrests are out.

The horn fuse spin it, or replace as corrosion from aluminum fuses cause problems. I suggest replacing them all with new copper barrel fuses. The blower motor fan is a strip fuse on the driver side strut mount in a tootsie roll sized case.

did you check to see if the a/c belt is still on the a/c puller ? if so then try a flush of all hoses.

check blowere motor resistor on or next to motor on passanger side

If the fuse is blown for the blower then there is a short, that is not an answer, go to the blower and check to see that the blower motor connector has 12 volts to it when the blower is set to high speed on control, if it does then u need a new blower motor, if it doesn't then the control switch is defective or the blower motor speed control resistor is defective.

hi,maybe the bushing of blower motor is defect,creating noise,by touching the blade to the housing,or the carbon brass is also defect,ty

eather blower motor went out or you need to replace the blower motor resister
