How to Install Vintage Air A/C into a Vintage Corvette - Page 10

The proof is in the pudding and, as this digital thermometer shows, the pudding is comfortably chilled at 57.9 degrees. The reading was taken from the driver's console vent while idling. At higher revs the temperature gets a couple of degrees colder.

Here's how the controls operate:

• The system is off with both knobs pushed in and the fan speed switch (left knob) rotated to the full counter-clockwise position.
• For A/C, both knobs are pushed in and the fan speed switch is rotated clockwise to low, medium or high positions.
• For heat, the left knob is pulled out and the fan speed switch is rotated clockwise for low, medium or high positions.
• For defrost, the left knob is pulled out and the fan speed switch rotated for low, medium or high speeds and the heat/defrost knob (right side) is pulled out as well.
• The thermostat control (under the dash on the passenger side) controls the overall output temperature of the system.
