The blower motor just start to blow at low speed i beleave it the blower resistor what should it cost to repair this problem
my ac blower motor blow at low speed lateley on 1997 Mercedes-Benz E320
usually the resistor burns out it only works on high
I would guess it to be the fan speed regulator. My records indicate 9 out of 10 times when it's low speed only, I've replaced the regulator for a proper repair. Be sure to check the current draw on the blower motor as it may be high creating undo stress on that particular circuit.
is this a big job and does it cost a lot to fix, my fan only blows on the low speeds Thanks
