Blower motor
 

On my 2011 GL 450, the blower motor stopped working. It is not the motor, I verified that there is no power going to the blower motor. So, I checked all fuses and replaced the climate control unit. I still cannot get power to the blower motor. Does anyone have any suggestions on what to try next?

The blower motor resister gets voltage requests from the AC controller if the controller, resister and blower are not faulty the system should function---very simple circuit.

And that is why it is frustrating. The fuses are good, new blower motor unit, and new climate control unit. I still have no power going to blower motor.

Is there a resistor or relay that I am missing? I've researched, and there does not seem to be a separate blower motor resistor on this particular model. 2011 GL450

Anyone else ever run into this problem? I'm sure it is possible, but, unlikely a broken wire??

Did you ever resolve the issue with the blower motor or the fuse/relay ? Thanks in advance.

ballast overheat??
 

if you have never replaced the cabin filter, the ballast module is now history. Located near the blower down there. Is that a bad $1 thermo fuse?
