On 2006 and earlier models, the turn signal and hazard flashers are controlled from a single electronic flasher unit mounted to the right of the steering column under the instrument panel, while 2007 and later models incorporate the flasher function into a Generic Electronic Module called the Smart Junction Block, which manages various exterior lighting functions. When functioning properly, the flasher unit emits an audible click; if the turn signals fail on one side and the clicking sound is absent, it suggests a faulty turn signal bulb. If both turn signals do not blink, potential issues could include a blown fuse, a faulty flasher unit, a broken switch, or a loose connection, and a blown fuse should prompt a check for wiring shorts before replacing it. To replace the flasher, disconnect the electrical connectors and remove the screw securing the flasher retaining bracket, ensuring the replacement unit matches the original before installation, which follows the reverse of the removal process.

Both the turn signals and the hazard flashers are controlled by an electronic flasher unit which can be found on 2001 and earlier models just below the steering column near the instrument panel on the right, or on the 2002 model behind the glove box in the relay #1 box. In normal condition, there is sound which is similar to a click during operation of the flasher unit. However, if the side turn signal indicator blinks much faster than usual the car's turn signal bulb is burnt out. If both signals do not blink, it is a problem with the bulbs if the fuses are blown; the flasher unit; the switch is broken; or if there are loose or open connections. Examining the fuse box and looking for a turn signal fuse that has blown is helpful and it is advised that before putting a new fuse in you look at the wiring and see if there is a short. For 2006 and later models, there are two fuses related to the turn signal lighting: There is one for the hazard flasher circuit and one for the turn signal circuit. For the flasher, there are plugs and sockets; to de-assemb1e simply unplug the connections and remove the screw of the flasher restraining clip. Make sure that the kind of unit assembled in the circuit is the same as the one removed by comparing it before fixing it which is done in the reverse way to the removal process.

The turn signal switches and the hazard flashers are handled by a flasher relay, This particular component is located inside the fuse block and is available within the previous models up to 1993 while in the subsequent models 1994 and beyond this relay is sited within the instrument panel near the steering wheel column. But when working properly the flasher relay makes a clicking sound when the operation is in progress. If the turn signals do not work on one side, and the relay does not click it indicates that the turn signal bulb is bad. In case of non- blinking of both the turn signals, the problems can range from a fused out circuit, a faulty flasher relay, a defective switch or a bad connection. If the problem is in the turn signal fuse then one should pop the hood and check the fuse box to see if the turn signal fuse is blown then check the wiring for shorts before replacing the fuse. To replace the flasher relay the negative cable of the battery should be disconnected, then flasher has to be removed either by pulling it right out of the fuse box or electrical connector, and then one has to make sure that the new flasher is an exact match with the original flasher which has to be then installed in the fuse box or the instrument panel connector.

Terminals 85 and 86 are normally the control circuit. If the relay contains a diode, terminal 86 must be connected to battery positive (B+) voltage and terminal 85 to ground. If it contains a resistor, terminals 85 and 86 can be connected in either direction.

Remove the flasher by pulling it straight out.

Disconnect the negative cable from the battery.

If the relay contains a resistor, the resistance will be indicated on the meter and should be the same value in either direction.

Refer to the wiring diagram for the circuit to determine the proper connections for the relay you're testing.

A faulty relay can be removed and tested using specific procedures or by a dealer service department or other repair shop. Defective relays must be replaced as a unit.

On most relays, two terminals are for the control circuit (connected to the relay coil) and the other terminals are for the power circuit (connected together when the control circuit coil is energized).

If the relay contains a diode, resistance should be higher with the ohmmeter in the forward polarity direction than with the meter leads reversed.

If a faulty relay is suspected, it can be removed and tested using the procedure below or by a dealer service department or other repair shop. Defective relays must be replaced as a unit.
