Ok so I recently got pulled over for my taillights being out. I replaced all the bulbs to the parking lights, tag lights, and third brake lights. Also tested a few switches trying to replace the headlight switch out because I saw that it could be a problem and still didn't work. I checked all my fuses and relays and everything's fine. I have no idea what it could be seeing how I've went through everything. So all my parking lights are out like taillights third brake lights and marker lights including my dash lights. I need the problem fixed quick and as soon as possible. Thanks in advance

 

It might help if you identified what you are working on.

What does that actually mean? Did you pull them out and stare at them, did you check for power with a meter, or what?

 

I pulled them out looked at them, then tested them with a meter. Also checked the connections where the fuse plugs in and it's a 2002 Ford F-150 FX4 with auto headlights and fog lights

 

Did you use your VOLTMETER and actually check for POWER at the relevant fuses or at the output of the headlight switch?

That is what is required to actually KNOW what is going on in the circuit. Report your readings (results), not your conclusion about them.\ unless you actually understand what is happening.

 

I found that I don't have any power going to the dimmer switch. Coming from the plug there is absolutely. nothing

 

I give up, I cannot work without specific details.

Good luck.
