What to Do When Your Toyota Pickup Corner Lights Malfunction
Corner lights, which are also called as side marker lights, are not mere ornaments found on the side of the fender. Just like all automotive lights found in your Toyota pickup, these lights are designed for a safety purpose-they enable other drivers to see you even at oblique angles. However, corner lights eventually start malfunctioning due to defects in their components. Check the following parts to find out why your Toyota Pickup corner lights have become inoperative:
Locate the fuse of your corner light in the fuse box, which can be found in the engine compartment. If the fuse is blown, replace it immediately. Pull out the old fuse using a fuse extractor. Make sure that your replacement fuse has the same amp as the old one and that it is of the same type. If you are uncertain about the kind of fuse you need, better consult your owner's manual.
In order to access the corner light bulb and have it examined, you need to remove the seals or covers placed on it. If there is any damage on the bulb, disconnect the wiring connector of the bulb and simply pull it from the assembly. Replace the burnt-out bulb. Make sure that your bare hands do not make any contact with the new bulb. Oil might get on the surface of the bulb, which could form into hot spots once the bulb heats up. Eventually, the bulb might burn out prematurely. You may use a clean cloth to hold it during installation.
Also, you may want to inspect the seals or covers for damage. Making sure that they are still in good condition would assure you that moisture or any dirt won't be able to get into the interior of your corner lights. Replace them as well if they are already worn out. Reconnect the wiring connectors.
Other possible damaged components
Other components that you might have to look into include the bulb socket. Make sure it is clean and free from rust. If corrosion is apparent, replace the affected part. Check the electrical terminals and other wires for corrosion as well. Also, make sure that there is sufficient voltage in the corner light's electrical connector. Otherwise, the problem might be caused by a battery or alternator malfunction.
