Where is the turn signal relay located

Hi Bernard:
The FLASHER is located under the driver dash it is a round fuse (it's located adjecent to the fuse block, and it's square, yellow in color).

Also, I suggtes to check for power at the junction box under the dash at terminals 1 and 6 with the combination flasher removed. Then check with a powered test lamp if test lamp lights pin 7 when signaling left and pin 8 when signaling to the right.

If the test results are correct, replace the Combination Flasher/DRL (Daytime Running Lights) module.



Gain access to the multifunction switch connector. Locate the Light Blue/Yellow wire and ground it. This should activate the right side turn signals. Locate the Light Blue/White wire and ground it. This should activate the left side turn signals. If both sides do work, the problem is in the multifunction switch. Verify the Black wire in the same connector is grounded at all times. If so, replace the multifunction switch.



Here is some reading on how the system works.

ELECTRONIC DAYTIME RUNNING LIGHT (DRL)
The Combination Flasher/DRL is a module providing turn signal, hazard warning, and daytime running light functions (for Canadian vehicles), and has been designed with internal relays to take advantage of low current switching requirements in the vehicle. It is plugged into the junction block at positions three and four, where all wiring associated with its operation is terminated. The junction block is adjacent to and left of the steering column of the vehicle.

On vehicles built for use in the United States, only position four is used. Vehicles built for use in Canada utilize both positions three and four.

To gain access to the device, remove the lower steering column cover and knee blocker.

The combination-flasher/DRL may be operated in its hazard warning mode either with or without the ignition circuit being active. However, in order to operate in the turn signal mode or the DRL mode, the ignition circuit must be completed to the module.

While the combination-flasher portion is idle, there is no current drawn through the module. The device does not become active in the turn signal or hazard warning modes until a signal ground circuit is supplied to either of the turn signal inputs or the hazard warning input. With the ignition OFF, there is no current drawn through the module.

While the ignition is ON, the front turn signal filaments are illuminated steadily thus providing the DRL function. The DRL function may be inhibited by applying a signal ground input from either the park brake circuit or the headlamp relay activation circuit.

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
