Auxiliary Heating System

Blower Speed Control

The three-speed blower switch ("LO-MED-HI") is located in the instrument panel, above the radio. In addition to controlling blower motor speed, the switch also triggers an electro-mechanical valve to control coolant flow to the auxiliary heater core.

Blower switch and valve positions are:

- OFF-Valve closed
- LO-Valve open
- MED-Valve open
- HI-Valve open
