Ford F75Z-19986-BA Switch Assembly

Disconnect the cable(s) from the negative battery terminal(s). Remove the instrument cluster trim panel or center trim panel. Remove the A/C Switch retaining screws. To detach the A/C Switch, remove these four screws. Pull the switch out far enough to disconnect the electrical connectors and the vacuum harness connector. Pull out the A/C Switch far enough to disconnect the four electrical connectors and the vacuum harness connector. Remove the switch. Installation is the reverse of removal. Verify that all controls operate correctly.

Before removing the radio and controls, pull out the A/C Switch from your instrument panel by first taking out the screws that keep it in place and removing the trim. When the automatic temperature control system comes as an option, its control unit will include a separate microprocessor. Some cars include extra controls either in the dashboard or steering wheel. The EATC system can check its own problems. To work on the control assembly, remove it from the instrument panel first. Then disconnect each electrical connector and vacuum line gently by lifting up the plastic clips and detaching them with care. Avoid breaking the plastic connectors to prevent vacuum leaks. Tear off three plastic grips in the back of the control panel to take out the speed switch, function selector, and blend-control switch. As you pull them forward, their front knobs stay attached. The car's optional rear heating/air-conditioning package has two control panels: one up front where the driver controls the front climate, and another behind for the rear passenger compartment with cool air or heat only. You follow the same steps to install the switches as you did for taking them off.

To reinstall, follow the reverse of the removal procedure. Be careful during installation to ensure all electrical connectors and vacuum lines are properly connected to avoid any issues.
