Turn signal/four ways not working

Hi and thanks for using 2carpros.com.

Since they work for a few times, it isn't a power issue. That leads me to believe it may be related to the flasher. Here are the directions for removing and testing the flasher. The three attached pictures correlate with the directions.

I noted that you indicated no knowledge. So, here are directions for testing wiring.

COMPONENT TESTS AND GENERAL DIAGNOSTICS
Inspection

1. Disconnect the negative (-) battery terminal.
2. Remove the driver crash pad lower panel (A).
3. Remove the driver crash pad reinforcing panel (A) after loosening 5 bolts.
4. Remove the flasher unit (A) after loosening the bolt and disconnecting the connector.
5. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 3.
6. Connect the two turn signal lamps in parallel to terminals 1 and 3. Check that the bulbs turn on and off.

NOTE:
The turn signal lamps should flash 60 to 120 times per minute. If one of the front or rear turn signal lamps has an open circuit, the number of flashes will be more than 120 per minute. If operation is not as specified, replace the flash unit.

If you feel the directions are confusing, honestly, the flasher isn't too expensive to replace. You may want to just try that. However, I added the test directions in case you want to confirm that is the problem.

Let me know if you have other questions or need help.

Take care,
Joe
