Throttle Full Open Switch HVAC: Description and Operation

The kick-down function switches off the A/C compressor for 12 seconds when activated. A/C kick-down is controlled by:

-

A/C kick-down switch, F46 on vehicles with 3-speed automatic transmission.

-

Automatic transmission control unit, J217 on vehicles equipped with 4-speed automatic transmission.

The A/C kick-down switch is located under the accelerator pedal on vehicles equipped. It will activate when the accelerator pedal is pressed toward the
floor. The kick-down switch will close and send a ground signal to terminal 9 on rear of the A/C control head.
