The power window system applies to Honda Civic EX and Si models between 1992-1995.
A permanent magnet motor operates each power window. The driver’s master switch assembly controls all power window motors. Each window switch controls only one power window motor. If main switch is in OFF position, only driver’s window may be operated. Passenger’s window cannot be controlled by rear window switches, but can still be controlled from driver’s master switch.
AUTO mode permits driver’s window to be fully lowered with a single touch to the switch. Moving switch past its first stop will engage AUTO mode. AUTO mode is controlled by a pulser integrated into driver’s window motor assembly. Pulser cannot be serviced separately. Power window control unit is integrated into power window master control switch. Control unit cannot be serviced separately.
DRIVER’S SIDE WINDOW MOTOR TEST
Remove door panel. Unplug 4-pin connector from motor. Using jumper wires, connect terminals No. 3 and 4 to battery voltage and ground. See figure. Check for motor operation. Reverse jumper wires and retest. Replace motor if it does not operation in both directions.
PASSENGER SIDE WINDOW MOTOR TEST
Remove door panel. Unplug 2-pin connector from motor. Using jumper wires, connect connector terminals to battery voltage and ground. See figure. Check for motor operation. Reverse jumper wires and retest. Replace motor if it does not operate in both directions.
PULSER TEST (DRIVER’S WINDOW MOTOR)
Pulser is integral part of driver’s window motor assembly. If pulser is defective, motor assembly must be replaced. Connect test leads of analog ohmmeter to motor connector terminals No. 1 and 2. Using jumper wires, connect terminals No. 3 and 4 to battery voltage and ground. See figure. If ohmmeter needle does not move back and forth while motor is operating, replace motor.
SWITCH INPUT TESTS
Some wires have been assigned a superscript to distinguish them from other wires of the same color. For example, Yellow/Green(1) wire is not the same as Yellow/Green(2) wire.
Turn ignition off. Remove driver’s door panel. Unplug connectors from master switch. Using a DVOM, perform appropriate switch input tests. See figure 1 or figure 2. If all input test results are okay, inspect connector and terminals for damage and proper fit. If connector is okay and power windows still malfunction, replace master switch.
MASTER SWITCH TEST
Remove power window master switch. Using an ohmmeter, check resistance of switch terminals with switch in
indicated positions. If continuity is not as specified, replace switch. See Master Switch removal and installation on bottom of this page. See figure 1 or figure 2.
POWER WINDOW MASTER SWITCH TEST (COUPE)
POWER WINDOW MASTER SWITCH TEST (SEDAN)
PASSENGER WINDOW SWITCH TEST
Remove power window master switch. Using an ohmmeter, check resistance of switch terminals with switch in indicated positions. If continuity is not as specified, replace switch. See figure 1 or figure 2.
- Position: Off
- Pin Continuity: “A” and “D”; “B” and “C”
- Position: Up
- “B” and “C”; “D” and “E”
- Position: Down
- “A” and “C”; “D” and “E”
POWER WINDOW RELAY TEST
Remove power window relay from underhood fuse/relay box. Using jumper wires, connect terminals “C” and “D” to battery voltage and ground. See figure. If continuity does not exist between terminals “A” and “B”, replace relay.
TROUBLE SHOOTING
All Honda Civic 1992-1995 models are equipped with Supplemental Restraint System (SRS). SRS wiring harness is routed close to instrument cluster, steering wheel, and related components. All SRS wiring harnesses are covered by Yellow outer insulation. DO NOT use electrical test equipment on these circuits. Before working on steering column components, disable air bag system.
Ensure all component terminals and ground connections are clean and tight. Check possible faults in order listed. Repair or replace components and circuits as necessary. Some wires have been assigned a superscript to distinguish them from other wires of the same color. For example, Yellow/Green(1) wire is not the same as Yellow/Green(2) wire.
- All Windows Don’t Work - Blown fuse No. 14 (20-amp) in underhood fuse box. Power window relay. Open in Black/Yellow or White/Red wires.
- Drive’s Window Doesn’t Work – Blown fuse No. 5 (20-amp) in underhood fuse box. Faulty driver’s window motor. Faulty window regulator. Faulty master switch. Faulty master switch input. Open in White/Yellow wire.
- Driver’s Window Doesn’t Work in Auto – Faulty pulser (in driver’s window motor). Faulty power window master switch. Master switch input. Open in Blue wire.
- Passenger Window Doesn’t Work – Blown 20-amp fuse(s) No. 8 (right front), No. 4. (right rear) and/or No. 7 (left rear) in underhood fuse box. Faulty power window master switch. Faulty passenger’s switch. Faulty passenger’s window motor. Faulty window regulator. Open in Blue/Black wire for right front, Green/Black wire for left rear and/or Yellow/Black (right rear) wire.
MASTER POWER WINDOW SWITCH REMOVAL AND INSTALLATION
Remove left front door panel. Unplug electrical connectors. Remove master switch mounting screws. Remove master switch. To install, reverse removal procedure.

do you have a power window circuit wiring diagram of honda ex, si civic 1995 model. Im converting my honda civic ex, si to power window. im going to manually lay out wiring harness. pls help. I need a power window circuit diagram for honda civic ex si 95 model sedan. i have a right hand power window master control.
I have a 1992 Civic. My main power switch on the driver side that controls the windows is not working right. It will roll down both of the rear windows but not the front, the passenger front will roll down from the passenger switch but not from main control on driverside . My power door lock from the driver side, it’s the only switch I have for power lock doesn’t work either. Is this all linked together?? I’ve checked the fuses inside the car, they were good. I’ve bought a master switch for the windows and also new motor nothing has worker. Thanks for your time,let me know if you can help. ADAM
