ABSTRACT:
A motor vehicle door lock defroster attachment is disclosed for use in defrosting frozen door linkage mechanisms. The device includes a flexible radially corrogated tube having an attachment end shaped to engage the nozzle of a portable gas torch and a tapered discharge end positionable within the elongated space defined by the vehicle's door and door jamb. When the attachment end has been connected to the torch nozzle and the discharge end positioned in the door space in the vicinity of the frozen door linkage mechanism, heated air will move through the tube and out the discharge end thereby warming and defrosting the frozen mechanism. In an operational embodiment of the invention, the defroster apparatus also includes a base which will adjustably grip the torch tank such that the tank is maintained in a substantially vertical orientation, and magnetic stripping which, when applied over the door space above and below the point of air infusion, will maintain the infused heated air in the general vicinity of the frozen linkage mechanism.
