I replaced one on a buddies car Mercedes had a redesigned blower and resistor it was a bit pricey but worked well in the end even came with a new cover to clear the motor. So if you need one i am sure they still can get you one, but from what i remember i am pretty sure it was the exact same code. Check the blower motor and see if its stuck and try different speeds to see if its the resistor. The Blower is on the passengers side and you will need to remove the kick panel. and then remove cover which i believe had 4 screws or torx screws, and remove blower see if frozen most times its the resistor.
