here is a question... 2012 740, same assembly, one day went out and got no front blower on any setting including high. worked fine day before, rear blower still comes on. i pulled the motor but how would i know if it is the resistor or the motor?
i tested the blower motor straight to a battery and it ran fine, tested the lead to the resistor and was getting 12v from car, nothing from resistor even when on full, so there ya go.
