Power Windows Ford Econoline E350

DESCRIPTION & OPERATION

The power window system consists of window switches, wiring and connectors. Power windows are operated by window switches. Reversible type motors are mounted with each individual window regulator. Each window has an individual switch for separate control. A master control switch is located on left front door or center console. All windows may be controlled from this switch.

Scheme 1

LUBRICATION

The door window mechanism should be properly lubricated to provide ease of operation. The window glass mechanism should be lubricated whenever the glass channel or window regulator is removed, or excessive effort is required to operate the windows. To lubricate a door window mechanism, apply an even coating of Multi-Purpose Grease to the window regulator rollers, shafts and the entire length of the roller guides as illustrated by the shaded areas.

DOOR GLASS (ECONOLINE)

Before making any adjustments, remove the door panel. See DOOR TRIM PANEL REMOVAL & INSTALLATION.

1. Loosen, but do not remove, upper regulator retaining nuts.
2. Raise glass to full up position and tighten nuts to 6-10 ft. lbs. (8-14 N.m).
3. Loosen, but do not remove, rear glass retainer bolt.
4. Move glass to rearward position and tighten retainer bolt to 6-8 ft. lbs. (7-11 N.m).
5. (Scheme 2)

Scheme 2

TAILGATE GLASS (BRONCO)

Fore-and-aft adjustments can be made after opening the tailgate by loosening the back window side glass run attaching screws (two per side). Adjust the glass as required and tighten the attaching screws to 6-11 ft. lbs. (9-14 N.m).

POWER WINDOW MOTOR

1. Disconnect the motor lead.
2. Disconnect the regulator mechanism from the motor.
3. Supply power to motor lead connector with an ammeter. (Scheme 3)
4. Operate the motor and observe the current draw. The current draw for the no-lead test should not exceed four amps and should not fluctuate. Reversal of the motor wire connections will reverse the direction of motor rotation. Replace the motor if the current draw exceeds four amps.

Scheme 3

POWER WINDOW SWITCH (BRONCO & PICKUP)

The switch should be removed from the vehicle, and should be oriented so that the raised portion of the switch knob is to the right and you are looking at the five terminals.

1. Use a self-powered test lamp or an ohmmeter to test the power window switch.
2. With the switch in the neutral position, there should be continuity between terminals 1 and 2, and terminals 3 and 4. Terminal 5 should be disconnected from all other terminals.
3. When the raised portion of the switch rocker knob is pushed (to close the windows), there should be continuity between terminals 1 and 5, and terminals 3 and 4. Terminal 2 should be disconnected from all other terminals.
4. When the depressed portion of the switch rocker knob is pushed (to open the windows), there should be continuity between terminals 1 and 2, and terminals 4 and 5. Terminal 3 should be disconnected from all other terminals.
5. If the switch assembly does not test as stated, replace the switch.

Scheme 4

Multiple Switch (Econoline, Left Side)

1. Clip one test lead probe on terminal No. 6 which is grounded. (Scheme 5)
2. With both switches in the neutral position, terminals No. 1 through 4 should have continuity to terminal No. 6.
3. Push both window switches upward (toward window when in installed position). Both terminal No. 1 and 3 should have no continuity to terminal No. 6.
4. Push both window switches downward (away from window when in installed position). Both terminals No. 2 and 4 should have no continuity to terminal No. 6.
5. Remove the test lead from terminal No. 6 and connect to terminal No. 5 (hot feed terminal). With both switches in the neutral position, terminal No. 5 should have continuity only with itself.
6. Push both window switches upward (toward the window when in installed position). Both terminal No. 1 and 3 should have continuity to terminal No. 5.
7. Push both window switches downward (away from the window when in installed position). Both terminals No. 2 and 4 should have continuity to terminal No. 5.
8. If any one switch does not test as stated, replace the complete switch assembly.

Scheme 5

Single Switch (Econoline, Right Side)

3. With the toggle switch pushed downward, there should be continuity between terminals No. 2, 4 and 5, and 1 and 3. Terminal No. 6 should be disconnected from any other terminal.
4. With the toggle switch pushed upward, there should be continuity between terminals No. 2, 3 and 5, and 4 and 6. Terminal No. 1 should be disconnected from any other terminal.
5. If the switch does not test as stated, replace the switch.

Scheme 6

INSTRUMENT PANEL-MOUNTED TAILGATE SWITCH (BRONCO)

1. Use a self-powered test lamp, or an ohmmeter to test the power tailgate switch.
2. With the switch in the neutral position, there should be continuity between terminals No. 1 and 2, and terminals No. 3 and 4. Terminal No. 5 should be disconnected from all other terminals.
3. When the switch rocker knob is pushed up (to close the tailgate window), there should be continuity between terminals No. 1 and 2, and terminals No. 4 and 5. Terminal No. 3 should be disconnected from all other terminals. (Scheme 7)
4. When the switch rocker knob is pushed down (to open the tailgate window), there should be continuity between terminals No. 2 and 5, and terminals No. 3 and 4. Terminal No. 1 should be disconnected from all other terminals.
