DESCRIPTION
Ford power window system consists of reversible 12-volt motors in each front door, switches to operate motors, wiring harness and necessary connections. Driver's door multiple switch controls both windows.
MOTOR
- Remove door trim panel. Disconnect motor lead. Disconnect regulator mechanism from motor. Connect a power source (battery) to motor with an ammeter in series. Operate motor and observe current draw.
- Current draw should not fluctuate or exceed 4 amps. Reverse motor wire connections to observe reversed motor operation. Replace motor if current draw exceeds 4 amps.
Scheme 1
- Remove switch from vehicle. Using an ohmmeter or self-powered test lamp, clip a test probe to pin No. 6, which is grounded. (Scheme 1) Place both switches in neutral position and test for continuity between pin No. 6 and pins No. 1-4. (Scheme 1): Multiple Switch Pin Location Use ohmmeter or self-powered test lamp for test.
- Push both switches upward. Both pin No. 1 and No. 3 should lose continuity to pin No. 6. Push switches downward. Pin No. 2 and No. 4 should lose continuity to pin No. 6.
- Remove test probe from pin No. 6, and connect it to feed pin No. 5. With both switches in neutral position, no continuity should exist at remaining terminals.
- Push switches upward. Both pin No. 1 and No. 3 should show continuity with pin No. 5. Push both switches downward. Both pin No. 2 and No. 4 should have continuity with pin No. 5. If any switch does not test as indicated, replace complete switch assembly.
Single Switch Pin Locations Use ohmmeter or self-powered test lamp for test. Scheme 2
SINGLE SWITCH
- With the switch in the neutral position, use an ohmmeter or self-powered test lamp to test switch. Continuity should exist between terminals No. 1, 2, 3, and 5. Continuity should also exist between terminals No. 4 and 6. (Scheme 2)
- With switch pushed downward, continuity should exist between terminals No. 2, 4 and 5. Continuity should also exist between terminals No. 1 and 3. Terminal No. 6 should be disconnected from all other terminals.
- With switch pushed upward, there should be continuity between terminals No. 2, 3, and 5. Continuity should also exist between terminals No. 4 and 6. Terminal No. 1 should be disconnected from all other terminals. If switch does not operate as specified, replace switch.
Removal
- Disconnect battery negative cable. Remove door trim panel. Disconnect power window motor wire from harness connector. Using a 1/2" diameter drill bit, drill 2 holes in door inner panel at drill dimples, located opposite 2 unexposed motor drive retaining screws. NOTE: Check before drilling to ensure no wires are in line with holes to be drilled.
- Using 2 holes drilled in step 1) and existing access hole, remove 3 motor mount retainer screws. Push motor outward to disengage motor and drive from regulator gear. After motor and drive are disengaged, prop window in full up position. Remove motor and drive.
Installation
To install, reverse removal procedure. Tighten attaching screws to 50-85 INCH lbs. (5.6-9.6 N.m). Cover drilled holes with body tape. Ensure that door drain holes are clear.
- Insert a thin screwdriver between bezel and trim panel at either side of bezel. Carefully pry bezel from trim panel, and housing assembly will snap out.
- On left side switch, remove 2 retaining screws from bottom side of connector. Unsnap right side connector from housing. Pry switch from connector with a small screwdriver.
To install, position switch in connector, and press firmly. Reverse removal procedure to complete installation.
Removal & Installation
If replacement of a switch wire or switch connector is necessary, insert a needle-like tool into edge of pin hole and bend terminal in. Pull wire and terminal from connector. To install terminal in connector, open terminal and insert it in connector.
