Two models offered. Both models feature three speed motor, vacuum operated heater control valve, firewall grommets, wiring harness with knob style control, heater core fittings and instructions. Defrost units come with thin defrost outlets and duct hose.
ComPac heat unit has very slightly lower CFM fan (not enough to feel by hand) than the original heat only units but also takes up less room.
New Bi-Level heat unit gives you the option of having the heat on the floor, at the dash, for defrost, or all three. Heater is controlled by a single cable control switch for easy use and better performance.
