Repair Instructions

Issue: Dead Battery / Parasitic Draw

Identify the Draw
- Disconnect the negative battery terminal.
- Connect the multimeter in series between the battery terminal and the disconnected cable.
- Measure the current draw; should be below 50 mA.
- If above normal, start pulling fuses one by one to identify the circuit causing the draw.
Repair the Faulty Circuit
- Once identified, inspect the components within that circuit for shorts.
- Repair or replace any damaged wiring or components.
Reconnect Battery
- After repairs, reconnect the battery and test to ensure the draw is within normal limits.

Issue: Power Window Failure

Check Switch Operation
- Remove the door panel to access the window switch.
- Use a multimeter to check for power at the switch with the ignition on.
- If no power, trace wiring back to the fuse box.
Inspect Window Motor
- If power is present at the switch, check voltage at the window motor while pressing the switch.
- If no voltage, replace the window switch.
- If voltage is present but the motor doesn’t operate, replace the window motor.
Reassemble Door Panel
- Reinstall the door panel and test the window operation.

Issue: Inconsistent Headlight Operation

Check Headlight Bulbs
- Remove the headlight assembly and inspect the bulbs for damage or burnt filaments.
- Replace with the correct type of bulbs.
Inspect Wiring and Connectors
- Check the wiring harness and connectors for corrosion or damage.
- Clean contacts and replace any damaged wiring.
Test Headlight Relay
- Locate the headlight relay in the fuse box and test for continuity.
- Replace the relay if it fails to operate.
Reassemble and Test
- Reassemble the headlight assembly and test the headlights for proper operation.
