Mazda RX-7 Automatic Headlight Doors

Mazda RX7 1993-1995 FD3S

Headlights can be raised by turning on headlights, or by turning retractor switch to the ON position. Retractor relay provides power to retractor motors. If system does not operate, headlights can be raised or lowered using manual knob on top of each retractor motor.

WARNING: Before using manual knobs to raise or lower headlights, disconnect negative battery cable to prevent accidental operation of headlight retractor motors.

Before disconnecting negative battery cable, obtain code number from vehicle owner and deactivate audio anti-theft system.

ADJUSTMENTS

HEADLIGHT LID

Loosen headlight lid adjustment screws. See Fig. 1 . Adjust headlight lid so distance between headlight lid and body is as specified when headlight is lowered.

HEADLIGHT LID CLEARANCES

1: .13-.26 (3.4-6.6) Inches (mm)
2: -.06-.06 (-1.6-1.6) Inches (mm)
3: .14-.26 (3.5-6.5) Inches (mm)
4: -.03-.09 (-.75-2.3) Inches (mm)

COMPONENT TESTING

RETRACTOR MOTOR

1. A link connects retractor motor to headlight assembly. Disconnect link from headlight assembly. Disconnect retractor motor 4-pin connector. Apply battery voltage across terminals "B" (positive) and "A" (negative) of retractor motor connector. See Fig. 2 . Leave battery voltage connected across terminals as specified.
2. To raise headlight, apply battery voltage across terminals "C" (positive) and "A" (negative) of retractor motor connector. To lower headlight, apply battery voltage across terminals "D" (positive) and "A" (negative) of retractor motor connector. If retractor motor does not operate as specified, replace retractor motor.

RETRACTOR SWITCH

Disconnect retractor switch 6-pin connector (remove switch, if necessary). With switch turned off, continuity should exist between terminals "A" and "C". See Fig. 3 . With switch turned on, continuity should exist between terminals "B" and "C". Continuity should also exist between terminals "E" and "F" with switch turned off or on. If continuity is not as specified, replace retractor switch.

RETRACTOR RELAY

Remove retractor relay. Check continuity between specified terminals of retractor relay 6-pin connector. See Fig. 4. If continuity is not as specified, replace retractor relay.

RETRACTOR RELAY TEST

Relay Not Energized: "A" and "B" and "C" and "E"
Relay Energized: "C" and "F"

TROUBLESHOOTING

Both Retractors Inoperative Using Either Switch: Test No. 1
Both Retractors Inoperative Using Headlight Switch: Test No. 2
Both Retractors Inoperative Using Retractor Switch: Test No. 3
One Retractor Inoperative: Test No. 4

TEST NO. 1

1. Check HEAD and RETRACTOR fuses in main fuse block. If fuse is faulty, replace fuse (repair circuit if shorted). If fuse is okay, disconnect retractor switch 6-pin connector. Measure voltage at terminal "C" (Red wire) of retractor switch connector. See Fig. 3 . If battery voltage is not present, repair wiring between HEAD fuse and retractor switch.
2. If battery voltage is present, disconnect retractor motor 4-pin connector. Measure voltage at terminal "B" (Black/White wire) of retractor motor connector. See Fig. 2 . If battery voltage is not present, repair wiring between RETRACTOR fuse and retractor motor.
3. If battery voltage is present, check continuity between ground and terminal "A" (Black wire) of retractor motor connector. If continuity does not exist, repair wiring between retractor motor and ground. If continuity exists, check retractor motor. If retractor motor is okay, go to next step.
4. Disconnect retractor switch 6-pin connector (remove switch, if necessary). With switch turned off, continuity should exist between terminals "A" and "C". See Fig. 5 . With switch turned on, continuity should exist between terminals "B" and "C". Continuity should also exist between terminals "E" and "F" with switch turned off or on. If continuity is not as specified, replace retractor switch. If continuity is as specified, repair wiring between retractor switch and retractor motor.

TEST NO. 2

Remove retractor relay. Turn on headlight switch. Measure voltage at terminal "A" (White/Green wire) of retractor relay 6-pin connector. See Fig. 6 . If battery voltage is not present, repair wiring between headlight relay and retractor relay. If battery voltage is present, check retractor relay. If retractor relay is okay, repair wiring between retractor relay and ground.

TEST NO. 3

Check retractor switch. If retractor switch is okay, repair wiring harness.

TEST NO. 4

1. Disconnect retractor motor 4-pin connector. Measure voltage at terminal "B" (Black/White wire) of retractor motor connector. See Fig. 2 . If battery voltage is not present, repair wiring between RETRACTOR fuse and retractor motor.
2. If battery voltage is present, check continuity between ground and terminal "A" (Black wire) of retractor motor connector. If continuity does not exist, repair wiring between retractor motor and ground. If continuity exists, replace retractor motor.
