Having trouble finding the blower motor control module on my Daughter's 2007 c280. Any help would be greatly appreciated.

 

Hi Everyone, I am hoping some of you may be able to help me.. And yes I have done study.
Problem is that the other day after returning house and exiting the vehicle, the blower motor continued to run even without the key being in the ignition. I researched potential problems on Google and it seemed the possible problem was the Blower Motor Control Module. Can any one of your give me idea in that issue?
