The turn signal switch is usually a part of a multifunction switch located in the steering column beneath the steering wheel (see Figure 32.23). SIGNAL FLASHER OPERATION There are usually two flashers, one for the turn signals and one for safety hazards.Turn Signal and Hazard Relay Circuits A typical turn signal and hazard relay wiring diagram is illustrated in Figure 1558. The diagram illustrates the system as it would be with ENGINE STOP SWITCH STARTER SWITCH IG BAT ST IG BAT4 HL OFF FREE PUSH Figure 1557 In.this illustration, the engine stop switch is connected when in the on position and the (electric) starter switch creates an open to the headlight (HL) when it is being pushed. This allows maximum current to be STOPLIGHTS WILL NOT TURN OFF Step 1 . Disconnect connector from stoplight switch. If lights go out, reconnect connector and adjust stoplight switch for proper contact with brake pedal. (See paragraph 416, INSTALLATION) If lights remain on, replace switch (See paragraph 416) If lights remain on after disconnecting connector, trace circuit. (See wiring diagram F14, F15, or F17) 40. TURN SIGNALS INOPERATIVE (HAZARD WARNING LIGHTS OPERATE) Step 1 . Remove turn Your car's turn signals work normally, but when the hazardwarning.switch on the steering column is pulled, the hazardwarning bulbs do not light or flash. The service manual provides an electrical schematic of the hazardwarning system. (The one shown here is similar to that of most modern cars.) The fuse checks out okay. Perhaps the hazardwarning flasher is bad? No— pulling out the old flasher and plugging in a new one doesn't help. Is electricity reaching the flasher? Yes.The signal lights will use the brighter stoplight filament. Turn Signal Switch Connections The wiring harness is now hooked up, but a couple of details may still be left to finish. If you have made the signal light conversion, one step that remains is installing the turn signal switch. Correct vintagelooking switches that.attach to your truck's steering column and can be tied into the wiring harness — if you installed a harness that included the signal light hookups — are available from your control box to the fuse block (19) and to a green wire that provides power to the stop, turn and flasher functions discussed below. Consider first the case where the turn signal switch (26) is in the central position so that none of the turn signals are operating. However, when the turn switch is operated, it activates a relay on the relevant side that disconnects the brake lamp circuit on that side alone and connects both front and rear turn lamps on the same side to the flasher module.This is a complete reference guide to automotive electrics and electronics.Figure.1619. Typical Turn Signal Wiring Diagram. Figure 1621. Typical Backup Light System. Figure 1618. Typical Turn Signal Switch. (2) A common design for a turn signal system is to use the same rear lamps for both the stop and turn signals. This complicates the design of the switch somewhat. Note that the stoplight circuit must pass through the turn signal switch. When the turn signal switch is turned off, it must pass stoplight current to the rear lamps.

Figure 1458 shows a typical turnsignal and hazard relay wiring diagram. The diagram illustrates the Before you start to troubleshoot either the turn signal switch, the emergency flasher switch, or the turn signal /emergency flasher relay, be sure that all bulb contacts are clean and tight. 6.1 Turn Signal and Emergency Flasher Troubleshooting The turn signals and the emergency flashers share the same flasher relay. The flasher relay is labeled "turn signal flasher" in the wiring diagrams that appear in 12.3 Wiring Diagrams. lt is located behind the kick panel to the.left of the driver's feet.
