Toyota Corolla 1988-1997 Repair Guide

Turn Signal and Hazard Flasher

Print

The combination turn signal and hazard flasher unit is located under the dash on the left side near junction block (No. 1). The flasher unit is not the classic round "can'' found on many domestic cars; instead, it is a small box-shaped unit easily mistaken for another relay. Depending on the year of your vehicle, the flasher may be plugged directly into the junction block (No.1) or it may be plugged into its own connector and mounted near junction block (No. 1). The flasher unit emits the familiar ticking sound when the signals are in use and may be identified by touching the case and feeling the "click'' as the system functions.

The flasher unit simply unplugs from its connector and a replacement may be installed. Assuming that all the bulbs on the exterior of the car are working properly, the correct rate of flash for the turn signals or hazard lights is 60-75 flashes per minute. Very rapid flashing on one side only or no flashing on one side generally indicates a failed bulb rather than a failed flasher.
