Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box under the dashboard and/or in the engine compartment.
Identify and remove the fuse for the power windows and door locks.
Inspect the fuse for any signs of a break in the filament; replace with an equivalent-rated fuse if blown.

3. Inspect and Clean Master Control Switch

Remove the trim panel surrounding the driver's side master control switch using a trim removal tool.
Disconnect the wiring harness from the switch.
Inspect for corrosion or damage; clean contacts with electrical cleaner if necessary.
If the switch is faulty, replace it with a new one.

4. Test Wiring and Connections

Reconnect the wiring harness and use a multimeter to check for voltage at the switch when the ignition is on.
If no voltage is present, trace the wiring back to the body control module, looking for shorts or open circuits.
Repair or replace damaged wiring as needed.

5. Final Assembly

Once repairs are completed, reconnect all connectors and secure the trim panel back in place.
Reconnect the negative battery terminal.
