The housing is in the form of a case having a hinged lid and an interior provided with a plurality of storage receptacles for storing and transporting a blower assembly and a pair of vent conduits. The blower assembly includes an electric fan for discharging air through two heated air outlet apertures. Preferably, electrical resistance heating elements are utilized to heat air within the blower assembly. The vent conduits comprise elongated flexible corrugated tubes each provided with a plurality of spaced vent apertures. The vent conduits are removably connectable to the blower assembly air outlet apertures. In use, the blower assembly and vent conduits are supported in spaced relation above a vehicle dashboard by a plurality of support stands. A power cord connects the blower assembly to the rechargeable battery, and a timer in the housing may be set to activate the blower fan and heating elements at a predetermined time to heat the interior of a vehicle and to defrost the vehicle windshield.
