My brights go off...

My brights go off and on and sometimes my headlithts just go off.

Mechanic's Assistant: Have you checked the fuses? Have you checked the bulbs?

I' ve checked the bulbs and they are good, But I haven't checked the fuses. Do you think it is fusrs or the relay for the lights.

Mechanic's Assistant: What year is your Relay?

2012

Mechanic's Assistant: Are you fixing your Relay yourself? What have you tried so far?

I can't afford a mechanic so I thought I would try to fix the problem myself.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I've had a problem with my drivers headlight and it has been in the shop but they couldn't find out why it was doing this.

trying to eliminate a ground problem possibility, when light go out, doe both of them go out together and does this occur with high beam and low beams?

they both go out but my main problem is the drivers side the bright headlights go out.
Auto Mechanic: Michael Broughton, Master ASE Technician replied 3 years ago

alright, so your high beams have a relay which you should check if this only occurs when using high beams and both lights go off together. if this occurs with your low beams as well then it must be in the switch (or the switches ground source). each headlight has its own ground. i'm going to send you a wiring diagram so you can see what i'm describing.

Auto Mechanic: Michael Broughton, Master ASE Technician replied 3 years ago

the reason it is important to know if they fail together and if its high or low (or both...) is that will tell you which circuit is failing, the low beams are BCM switched, the high beam share a single relay but do have individual fuses.

headlight ground is also separate for each lamp so if they go out together, it is not a haedlamp ground issue but could conceivably be a switch ground issue as the switch sends ground to BCM to signal a lamp request.

If i have answered your question, please ensure you rate my service, i get no compensation until i'm rated. we will still be able to communicate here if you have further questions about this.
