Ford F4DZ-19986-A Temperature Control

On 2001 and later models, turn the temperature control knob to the full cool position. Disconnect the negative cable from the battery. On 1994 and earlier models, remove the ashtray and the retainer bracket. On 1995 and later models, remove the radio. On 2001 and later models, remove the two screws that are located just above the climate control knobs that secure the cluster trim. For all years (with or without screws) pull the trim carefully as this will release the spring clips holding the trim on. Once the trim is released, disconnect any electrical connectors. Remove the four screws securing the A/C Switch to the instrument panel. Pull the A/C Switch through the opening in the instrument panel far enough to allow removal of electrical and vacuum connections. On 1995 through 2000 models, the assembly can now be removed from the vehicle. On 2001 and later models, pull the temperature control knob from the front. From behind, remove the screw that holds the switch with the cable then separate it as a unit from the A/C Switch. Remove the A/C Switch away from the instrument panel. Use a small screwdriver and remove the vacuum harness from the vacuum switch on the side of the A/C Switch. At the back of the A/C Switch, use a screwdriver or needle-nose pliers and disconnect the temperature and function cable from the white control bracket, if equipped. At the bottom of the A/C Switch, disconnect the temperature control cable from the control, if equipped. Pull enough cable through the instrument opening until the function cable can be held vertical to the A/C Switch, then remove the cable end from the function lever. Remove the A/C Switch from the instrument panel. Installation is the reverse of removal. If a new A/C Switch is installed, the original blower switch and function switch must be transferred to the new unit.
