The hazard flasher is located in the convenience center, installed in a clamp attached to the base of the steering column support inside the car. To replace it, unplug the old unit and plug in a new one.

Electrical circuits for the blinkers and the hazard indicators include small canister shaped flasher units. When these are functioning properly, they make an audible growl whilst the circuit is operating. Therefore, if only one side's turn signals fail and the flasher unit cannot be heard, this is indicative of a burnt-out bulb. On hearing the flasher unit an electrical short in wiring system is indicated. Signal failure on both sides could be due to a blown fuse or faulty switch or flasher unit or broken connection. However, check for a blown fuse before installing another one if it has burnt out. For turn signal lamps testing them like you test hazard warning lamps. The location of hazard warning flasher unit is in fuse box beneath the dash on right hand side. The steering column support serves as mounting base for turn signal indicator light flasher. Replacement should always be done by getting another that has the same capacity as those that have been already removed when either of such blinkers needs being put anew. It would always be wise to make sure that new one fits exactly into place where old was.

The flasher for the turn signals is a small canister-shaped unit positioned under the dash beneath the knee bolster or behind the glove compartment on vehicles made in 1999 and after. It sits next to a huge wiring splice and is held by plastic strap. When it works, there should be an audible click sound accompanying its operations. Where one side's turn signals fail without that characteristic clicking noise of the flasher, then a busted signal bulb exists. In case both stop lights stay on without blinking, this could be due to a blown fuse, a faulty flasher unit, a broken switch or loose or open connections. To replace flasher relay remove under-dash panel or knee bolster so as to unplug it from its socket. A new one must match the old in all regards. The hazard warning lamp assembly used for flashing all four turn signal lamps at once upon switching it on is situated inside instrument panel behind knee bolster or behind glove compartment on 1999 and later models too. It also abuts against large wire clamp and is held in place with plastic band. Checking procedure for hazard warning light unit resembles that of turn indicator unit described above. To replace it you will need to take off under-dash panel or knee bolster cover in order to unplug the flasher itself. The replacement lamp has to be exactly similar to the one being replaced.

First, several electrical accessories in the vehicle use relays to transmit the electrical signal to the component and if the relay is defective, that component will not operate properly. The various relays are grouped together in several locations like the engine compartment. If a faulty relay is suspected, it can be removed and tested.

To remove the switch of the turn signal, first of all disconnect the negative battery cable, then remove steering column covers and driver's knee bolster. Afterwards, remove the top two Torx screws securing a multi-function switch to a steering column. After that unclip the wire ties that secure it in place on other wires of the steering column. At the bottom of the steering column firewall bulkhead remove bolt holding large connections. Separate two multi-function switch connectors from large bulkhead connector. Remember that Multi-Function Switch and its harness should be replaced together as one unit. To install new switch just reverse removal process steps.

Flasher units control the turn signals and hazard lights. If one side's signals fail and no click is heard, it's likely a faulty bulb. If the click persists, it's a wiring short. If both sides' signals fail, it might be a blown fuse, faulty flasher, switch, or loose connection. Check for wiring shorts before replacing fuses. The hazard flasher is in the fuse box under the dashboard left side, while the turn signal flasher may be in the fuse box or under the instrument panel. Ensure replacement flashers match the original's capacity.

First, remove the necessary sound insulator panel(s) from under the instrument panel. Then, remove the flasher from the retaining clip and detach the wiring connector. To install the new flasher, attach the wiring connector to it and install the flasher in the retaining clip. Finally, reinstall the sound insulator panel(s).

If a relay is faulty, the corresponding component will not function properly.

If both turn signals fail to blink, it may be due to a blown fuse, a faulty flasher unit, a broken switch, or a loose or open connection.

It indicates a faulty turn signal bulb.

Remove the bolt that secures the large bulkhead electrical connector to the firewall.

The problem could be due to a blown fuse, a faulty flasher unit, a broken switch, or a loose/open connection.

Separate the two multi-function switch connectors from the large bulkhead connector.

If a relay is faulty, the corresponding component will not function properly.

No, the multi-function switch and its harness must be replaced as a unit.

In the case of a defective relay, it must be replaced as a whole unit.

To replace the turn signal flasher, the under-dash panel or knee bolster needs to be removed and the flasher needs to be unplugged. The replacement unit should be identical to the original.
