Section 12-00: Climate Control System, Service | 1996 F-150, F-250, F-350, F-Super Duty and Bronco, F-Super Duty Motorhome Chassis Workshop Manual |
The FS-10 A/C compressor (19703) is used on all F-Series and Bronco vehicles.
An A/C clutch (2884) is energized when the A/C cycling switch (19E561), located on the suction accumulator/drier (19C836), closes. The closing of the A/C cycling switch completes the circuit to the A/C clutch and draws it into engagement with the compressor driveshaft.
When the A/C cycling switch is closed and the control knob/lever is set at MAX A/C, NORM A/C, or either of the settings calling for full or partial defroster operation, the A/C compressor will be operating. (A/C compressor operation during defrost is provided to minimize humidity in the passenger compartment.) The A/C compressor is mounted on the side of the engine and is driven by a drive belt (8620) . Tension adjustment is obtained by means of an automatic tensioner (gasoline engines) or by moving the compressor braces away from the engine (diesel engines).
