Anti-Theft Vehicle Waterproofing Procedure

Vehicles with anti-theft require waterproofing of both front door key lock cylinder switch housings and the driver's door key cylinder switch-to-harness connector before proceeding with the Power Door Lock Signal and Wiring Check Procedure.

NOTE
USE CAUTION WHEN REMOVING THE METAL LOCK ROD BRACKET TO PREVENT THE BLACK SWITCH FROM FALLING OFF THE CYLINDER WHILE APPLYING GREASE. IF IT FALLS OFF, IT IS IMPORTANT TO MAKE SURE THE INDEX MARK ON THE GRAY OCTAGONAL SWITCH RING IS ALIGNED WITH THE INDEX MARK ON THE BLACK SWITCH HOUSING WHICH IS LOCATED IN LINE WITH THE BLACK GROUND WIRE.

NOTE
ONLY USE GREASE THAT IS "ELECTRICALLY NON-CONDUCTIVE" AND WILL NOT HARM PLASTIC PARTS, SUCH AS SILICONE BRAKE CALIPER GREASE AND DIELECTRIC COMPOUND (D7AZ-19A331-A, MOTORCRAFT WA-10 OR EQUIVALENT MEETING FORD SPECIFICATION ESE-M1C171-A).





1. With both front door trim panels still removed, remove the C-clip located on the back side of the door lock cylinder. Lift the metal bracket, which contains the lock rod, off the door lock cylinder. Generously apply dielectric grease to the back side of the key cylinder switch housing where the bracket makes contact with the key cylinder switch and reassemble (Figure 3).

2. Disconnect the driver's door key cylinder switch-to-harness connector located about 305 mm (12") from the door key cylinder. This is a 4-pin connector with three (3) wires. Pack grease into the back side of this connector, especially into the blank connector to prevent water intrusion. Do the same for the mating connector.

3. Reverse Steps 1-2 in this procedure and Steps 1-4 in the previous Service Procedure to reassemble the doors, then proceed to the Power Door Lock Signal and Wiring Check Procedure.
