[DiGabriela]

Right window defroster door motor exceeding the upper limit may be due to a damaged defroster vent motor. Damaged defroster vent motor: If you can feel warm air at the vent but it's not blowing out, this indicates the defroster motor is faulty. It is recommended to replace the motor. If you cannot feel the fan rotating or any air movement, and there is no heat at all, this means the entire defroster may be broken and a new car defroster needs to be installed. Function of the defroster: It provides interior heat to melt ice, snow, or frost on the windows. With it, you can clearly see outside the car in low-temperature winter environments.
