27D A/C Switch Circuit

1. Turn the ignition switch Off.
2. Disconnect black connector from logic module and connect voltmeter to cavity No. 11 of black connector and ground.
3. Turn the ignition switch to the Run position and turn the blower switch to an on position and the A/C button on.
4. If voltmeter reads within one volt of battery voltage, replace logic module.
CAUTION: Before replacing the logic module make sure terminal in cavity No. 11 is not crushed so that it cannot touch the logic module pin.
5. If the voltage is not okay, repair the wire of cavity No. 11 for an open circuit to A/C switch.
