Toyota 84332-34010 Switch Assy, Hazard Warning Signal

T100 drivers should look behind the bottom left part of their instrument panel to find the flasher unit. Working correctly, you'll hear a clicking sound from the flasher unit, but when only one side of the turn signal stops working and the flasher does not make its normal click, a bad turn signal bulb is most likely the problem. If both turn signals don't blink, it could be either of three things: a faulty turn-signal fuse that needs replacing, a defective flasher unit, cracked switch mechanism, or a loose wire connection. Examine the fuse box and replace the turn-signal fuse if it's blown. Also, examine the wire connections for shorts before installing a new fuse. Detach the left panel and disconnect the old flasher, then plug in a new one as a direct match for the original model before reversing the removal process. To see if the hazard warning works as it should, first remove the switch from the dash and unplug it. Then use an ohmmeter to make sure there's a connection (continuity) between the following circuit terminals: between terminals 2 and 3 to check the illumination circuit, and between terminals 7 and 10 when the switch is off, and between terminals 5, 6, and 9, as well as between If the hazard warning switch stops working, you need to replace it.
