So my wife’s ml350 blower motor stopped working suddenly, I have read posts n videos about it being the harness under the passenger floor not being able to handle the current wattage on the power wire , either it burns up or comes lose my question is what is the harness actually called to find a new one to replace it??

 

i’m not sure but to get mine working temporarily which is been a couple of times over the last year or so, I just stomp the right side of the passenger floor and the blower starts working again. Helpful for those hundred degree days in Texas.
