My turning signals/hazards are not working, will not turn on. I have no idea how to read the relay map. Not sure which one to check, checked the fuse and it is good. Help I am a nurse not a mechanic.

So the patient is alert and oriented X3 but cannot blink his eyes.

You will not find the flasher relay in the relay box. It is buried under the center of the dash in the blower flasher block. However, it is the first place to check for power to the system. If you do not hear it clicking for either function it is likely the culprit. The next most likely would be the multi-function switch. However, those usually give warning prior to failure. Do you have any test equipment like a test light or a voltmeter?

The turn signal not working cannot find the problem. I do not know which fuse to check.

Hi and thanks for using 2CarPros.

You need to locate fuse 23 in the central junction box. See the attached pictures. It is a 10 amp fuse.

Here are a couple links that may help:

Let me know if this helps.

Take care,

The signal light will blink once and then it stops lighting but you can hear a blinking sound. My head lights and hazard lights work. What could be the problem?

I would recommend you start by replacing the flasher relay. Attached image on location. Let us know if it worked. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
