A Toyota truck can experience a number of electrical faults over 20 years. One of the more persistent problems is the failure of some of the dashboard lights in the instrument panel. If a dash light fails you should look to replace the bulb as the light provides the driver with vital information when driving the truck. You can buy replacement bulbs at your local auto parts store.
Ensure the vehicle is turned off. Open and secure the hood of the vehicle. Disconnect the negative battery cable from the battery terminal followed by the positive cable, using a wrench, which will ensure safety while working on the truck's electrical system.
Locate the two screws attached to the rubber or plastic bezel, which lines the edge of the dashboard's instrument panel. Remove the screws, using the screwdriver, and carefully pull the instrument panel away from the dashboard.
Remove the three screws that hold the instrument panel in the dashboard. Place the screws in a safe place as you will need them later for reattachment. Slide the panel halfway out of the dash and stop.
Reach around the back of the instrument panel and unhook the electrical connector, which will allow you to remove the instrument panel from the dashboard.
Place the instrument panel on a flat work surface and carefully remove the damaged bulbs, turning counterclockwise. Install the new bulbs, turning clockwise until they are tightly in place.
Reconnect the electrical connector into the back of the instrument panel. Slide the instrument panel back into place in the dashboard. Reinstall the three screws that hold the instrument panel in the dashboard, using the screwdriver, turning clockwise.
Reinstall the dashboard instrument panel bezel. Reinstall the two bezel screws, using the screwdriver, turning clockwise.
Reconnect the positive battery cable, followed by the negative cable, using a wrench. Close the vehicle's hood.
