Rear heater vents - low flow (2003)
In the winter there is some heat coming out but again not much flow.
The booster fan works fine and so does the direction flap motor (vent or heater)
I have had my ML 350 looked at by the dealership. They tell me that I need a new motor and clip for controlling the rear heat/cool flow.
I was wondering where I could look to get at the flap that controls the air to the back.
Thanks

open the dash near driver feat. you'll see the motors (total 3 near feet). lowest one should be the rear motor. remove it (3 screws). most likely there is a broken (plastic) arm that needs to be replaced.
You can prior to removal test the motors by moveing the air direction and the same time holding the finger on motors. If you feel movement but no increase in air etc then it's the plastic arm. If no movement then it's the motor.
