Power Windows Ford Econoline E150

DESCRIPTION

Power window system consists of reversible 12-volt motors in each front door, switches to operate motors, wiring harness and necessary connections. On Bronco, a switch on the instrument panel controls the tailgate window.

MOTOR

  1. Remove door trim panel. Disconnect motor connection. Disconnect regulator mechanism from motor. Connect power source (battery) to motor with an ammeter in series. Operate motor and observe current draw.
  2. 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

Scheme 1: MULTIPLE SWITCH
Scheme 1: MULTIPLE SWITCH
  1. Remove switch from vehicle. Using an DVOM or self-powered test light, clip a test probe to pin No. 6, which is grounded. (Scheme 1) Place both switches in the released (neutral) position. Pin Nos. 1 through 4 should indicate continuity to pin No. 6.
  2. Push both switches upward. Pins No. 1 and No. 3 should lose continuity to pin No. 6. Push switches downward. Pins No. 2 and No. 4 should lose continuity to pin No. 6.
  3. Remove test probe from pin No. 6, and connect it to pin No. 5 (battery feed). With both switches in released (neutral) position, pin No. 5 should have continuity only with itself.
  4. Push both switches upward. Pins No. 1 and 3 should have continuity to pin No. 5.
  5. Push switches downward. Pins No. 2 and No. 4 should show continuity to pin No. 5. If any switch does not test as indicated, replace complete switch assembly.

SINGLE SWITCH

Note. (Scheme 2)through (Scheme 4) for single switch pin locations.

  1. With switch in released (neutral) position, continuity should exist between terminals No. 1 and 3, terminals No. 2 and 5, and terminals No. 4 and 6.
  2. With toggle switch pushed downward, continuity should exist between terminals No. 2, 4 and 5, and terminals No. 1 and 3. Terminal No. 6 should be disconnected from any other terminal.
  3. With toggle switch pushed upward, continuity should exist between terminals 2, 3 and 5, and terminals No. 4 and 6. Terminal No. 1 should be disconnected from any other terminal. If switch does not test as indicated, replace switch.

Bronco (Tailgate-Mounted)

  1. With switch in released (neutral) position, continuity should exist between terminals No. 1, 2 and 3.
  2. With the key rotated clockwise (window up), continuity should exist between terminals No. 1 and 5, and terminals No. 2 and 4.
  3. With key rotated counterclockwise (window down), continuity should exist between terminals No. 2 and 5, and terminals No. 3 and 4. If switch does not operate as specified, replace switch.

Removal

  1. 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. Ensure door wiring is not in line with holes to be drilled.
  2. 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 door drain holes are clear.
