Toyota 4Runner Turn Signal Assembly: Some Issues for Troubleshooting
Drivers are not mind readers. This is why you have all the signaling contraptions in your vehicle-to clue in other motorists of what your next move on the road will be. If your Toyota 4Runner turn signal assembly goes off, there's a chance that you could get into a fender-bender, receive a traffic offense ticket, or create monstrous traffic on the road. Unfortunately, your turn signal (also known as blinkers) will occasionally go haywire. Here are some of the things to watch out for and what you should do about them:
One of the turn signals has gone off
The first thing to check here-and this rings true for all other automotive lightings-are the bulbs. Burnt-out bulbs are one of the most common reasons why turn signals go off. Check the base of the bulb if it has darkened-that is an indication that the bulb has burned and needs to be replaced. Install a new bulb and test the blinkers if both would turn on.
Both turn signals are not working
Although bulbs rarely go off at the same time, it's not a bad idea to check the assembly for used-up bulbs. However, if the bulbs are not the issue, you might want to inspect bulb sockets for grounding. On other occasions, the fuse may be the problem. Replace the fuse of the affected blinker and test if the lights would work. If you find no issue with the fuse, check the electrical connections if they are loose or corroded.
Turn signals blink very quickly
Turn signals blink to indicate your next move on the road. If they blink too rapidly, you might have an incorrect bulb installed. Check the manufacturer's note on bulb wattage and compare it with your current bulbs' wattage.
Another reason for the rapid bulb blinking could be a bad combination switch. Voltage going to the turn signals may sometimes drop, causing the blinkers to flicker rapidly. Sometimes, the problem lies on the combination switch. Usually, the switch requires a little bit of cleaning in order for the blinkers to return to normal.
