DESCRIPTION
Note. This article includes Cutaway and RV Cutaway.
The power window system consists of window switches, window regulators, motors, wiring and connectors. Power windows are operated by window switches. Reversible type motors are mounted with each individual window regulator. A master control switch is located on the left door. All windows may be controlled from this switch. Passenger's window has an individual switch for separate control.

COMPONENT LOCATIONS
DOOR WINDOW GLASS
Remove door trim panel. Loosen upper window regulator bracket nuts. Raise window glass to full up position. Tighten upper regulator bracket nuts to 89-124 INCH lbs. (10-14 N.m). Loosen rear glass channel bolt. Lower window glass partially, to allow adjustment. Move window glass to rearward position. Tighten rear glass channel bolt to 62-89 INCH lbs. (7-10 N.m). Open and close window to verify proper operation.
TROUBLE SHOOTING
Verify customer concern by operating windows to duplicate condition. Ensure battery is fully charged. Ensure windows are properly aligned. Check for damaged window mounting, window frame interference, faulty fuse, open or shorted power supply circuit, loose or corroded connectors, poor ground connections, and faulty switches. If problem is found, repair or replace components as necessary. If problem is not found, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
SYSTEM TESTS
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. |
Note. Before beginning system tests, perform TROUBLE SHOOTING .
SYMPTOM INDEX
Scheme 1
Scheme 2
- Remove fuse No. 21 (30-amp) from instrument panel fuse block, located on lower left side of steering column. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and fuse No. 21 input terminal (left terminal) on fuse block. (Scheme 1) If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair Black/Light Green wire between instrument panel fuse block and ignition switch. Retest system operation.
- Turn ignition switch to LOCK position. Remove master window switch assembly. See «WINDOW SWITCH»(/ford/econoline/i-1985-2013/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Using an ohmmeter, check resistance between ground and all Black wires of master window switch assembly connector. If all resistance measurements are less than 5 ohms, repair open in Red/Light Blue wire between instrument panel fuse block fuse No. 21 (30-amp) and master window switch assembly connector C500 terminal No. 10. (Scheme 2) Retest system operation. If any resistance measurement is 5 ohms or more, repair open in Black wire(s) between ground and master window switch assembly connector. Retest system operation.
TEST B: DRIVER'S POWER WINDOW INOPERATIVE
- Remove and disconnect master window switch assembly. See «WINDOW SWITCH»(/ford/econoline/i-1985-2013/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and master window switch assembly connector C500 terminal No. 10 (Red/Light Blue wire). (Scheme 2) If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Red/Light Blue wire between master window switch assembly and instrument panel fuse block fuse No. 21. Retest system operation.
- Turn ignition switch to LOCK position. Using an ohmmeter, check resistance between ground and master window switch assembly connector terminals No. 7 and 12 (Black wires). (Scheme 2) If both resistance measurements are less than 5 ohms, go to next step. If any resistance measurement is 5 ohms or more, repair open in Black wire(s) between master window switch assembly and ground. Retest system operation.
- Reconnect master window switch assembly connector. Disconnect driver's door window motor connector. Turn ignition switch to RUN position. Using a voltmeter, check voltage between driver's door window motor connector White/Black wire and Yellow wire terminals with left window switch (on master window switch assembly) held in UP position. Check voltage with left window switch held in DOWN position. If voltage is 10 volts or less in either measurement, check for open or short to ground in White/Black or Yellow wire between master window switch assembly and driver's door window motor. If wires are okay, replace driver's door window motor and retest system operation. If voltage is more than 10 volts in both measurements, replace driver's door window motor and retest system operation.

Scheme 4
- Remove and disconnect passenger's door window switch. See «WINDOW SWITCH»(/ford/econoline/i-1985-2013/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and passenger's door window switch connector C600 terminal No. 3 (Red/Light Blue wire). (Scheme 3) If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Red/Light Blue wire between passenger's door window switch and instrument panel fuse block. Retest system operation.
- Turn ignition switch to LOCK position. Remove and disconnect master window switch assembly. See «WINDOW SWITCH»(/ford/econoline/i-1985-2013/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and master window switch assembly connector C500 terminal No. 11 (Red/Light Blue wire). (Scheme 4) If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Red/Light Blue wire between master window switch assembly and instrument panel fuse block. Retest system operation.
- Turn ignition switch to LOCK position. Using an ohmmeter, check resistance between ground and master window switch assembly connector C500 terminals No. 9 and 14 (Black wires). (Scheme 2) If both resistance measurements are less than 5 ohms, go to next step. If any resistance measurement is 5 ohms or more, repair open in Black wire(s) between master window switch assembly and ground. Retest system operation.

Using a voltmeter, check voltage between passenger's window switch connector C600 terminal No. 2 (Tan/Light Blue wire) and terminal No. 4 (White/Yellow wire) with right window switch (on master window switch assembly) held in UP position. Check voltage with right window switch (on master window switch assembly) held in DOWN position. If voltage in either measurement is 10 volts or less, check for open or short to ground in Tan/Light Blue or White/Yellow wire between master window switch assembly and passenger's door window switch. If wires are okay, replace master window switch assembly. Retest system operation. If voltage is more than 10 volts in both measurements, go to next step.

REMOVAL & INSTALLATION
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. |
- Disconnect negative battery cable. Remove door trim panel and watershield. Disconnect window motor wiring and window switch. Using care not to enlarge sheet metal holes in door inner panel, remove 1/4" rivets attaching motor bracket to inner panel. Use drift to knock out center pins from each rivet. Using 1/4" drill bit, drill out remaining rivet.
- Working through access hole, remove motor bracket from inner panel. Rotate bracket to gain access to 3 screws retaining window regulator and motor. Remove screws and separate window regulator and motor from bracket and cable drum housing. Remove window motor.
- To install, reverse removal procedure. Tighten motor mounting screws to 53-62 INCH lbs. (6-7 N.m). Install motor bracket to inner panel using 1/4x20x1/2" bolts, nuts and washers.
Disconnect negative battery cable. Gently pry up on rear of switch plate to remove switch housing from door trim panel. Remove 2 screws securing connector. Using thin-blade screwdriver, pry connector from switch plate. To install, reverse removal procedure.
