My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

From what you have described here this can be a fault with the brake light switch itself.If this switch has failed it will cause no brake lights to all brake light assemblies like you see here.My info isnt showing where this switch is on your model for sure but usually most are either on a bracket above the brake pedal or at the brake master cylinder area.I have had to replace several of these brake switches for this issue here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
