Hi All,

I have a 2013 E400, I noticed the other week that there was a vibration (similar to an inconsistent electrical buzzing) coming from the brake pedal. The cause seems to be the climate control as it goes away once the climate is off. It's not related to the A/C, If I turn off the A/C and leave the climate on the vibration is still there so I think it has something to do with the blower motor. I always drive with the Climate Control on so the motor could be worn however Im not sure why I would feel it in the brake pedal unless the motor Is located around that area...does anyone know?

Has anyone else had a similar issue?

Hi, I have never heard of blower motor causing vibration issue, I have only heard faulty blower motor causing noise issue.

The vibration you feel could be engine mount or transmission mount.

Take care

could be a duct or actuator or soemthing touching brake pedal or pedal mounting bracket

I thought it might be engine / trans mounts also however the vibration is the same if I have the A/C on or off, its the fan that seems to be causing the vibration.

Yea I think it might be an actuator or something near the brake pedal assembly that has to do with the climate, does anyone have a diagram of the climate system or know of anything near that area would cause that?
