Abstract
A circuit and method of reducing the occurrence of overheating of a power fold vehicle mirror. The circuit controls the operation of the power fold mirror such that when a portion of the circuit reaches or exceeds a predetermined temperature threshold, the vehicle mirror is prevented from at least folding in. In practice, the vehicle mirror will be allowed to fold out even when the predetermined temperature threshold has been reached or exceeded, to allow the vehicle door to be opened and the car to be driven. The vehicle mirror may be allowed to be folded in when the temperature of the circuit falls to or below a second predetermined temperature threshold.
