Headlights, high or low beams, taillights, parking lights, dash lights or interior lights are not working

Thanks for coming to 2CarPros with those questions. However, we need to submit a question for each one as others will not find the solutions under the same heading. Basically, we need to keep each question on one topic so that all others can easily find their solutions.

Let's start with the headlights so I am attaching the diagram below on what we need to do.

Basically, we need to start by checking the power leaving the light switch. We need to find out if the red/yellow wire is getting power.

If not, then the likely cause of this is a light switch. We need to pick one light circuit and figure that one out and it will most likely fix all the lighting issues, but it is overwhelming to try and look at all of them at the same time.

So, let's focus on this one first and go from there. Thanks
