<p>A circuit for controlling bi-directional operation of a vehicle window lift motor 12 having a toroidal coil 38 sensing counter-emf perturbations in the motor current line. An EXPRESS mode switch 98, upon momentary actuation, latches an electronic switch to operate a relay to provide continuous motor rotation for lowering the window. Subsequent momentary switch actuation unlatches the electronic switch to cut interrupt window motor current. Window lift motor stall is detected by a toroidal coil which senses loss of motor line perturbations and unlatches the electronic switch to open circuit the motor relay. <IMAGE></p> |
