Turn Signals and Emergency FlashersPower for the turn signal circuit is routed through the emergency flashers switch only when the ignition is on (terminal 15). The emergency flashers circuit receives power from the battery at all times. When the emergency flashers switch is on, the turn signal switch is bypassed. The turn signals and the emergency flashers share the same flasher relay, but each circuit has its own fuse. One system working indicates that the flasher relay is good. Look for a failed fuse. If both the flashers and turn signals are inoperative, then it is probably either the flasher relay or the emergency flasher switch that is faulty. Check to see if power is reaching the relay. Check the flasher switch by checking continuity in the ON and OFF positions, using the current flow diagram as a guide. For failed turn signals, test the turn signal switch as described in 10.2 Steering Column Switches. |
