2001 Dodge Ram 2500 Tail Lights Not Working

I replaced the flash relay in the cab fuse box and all this started.

2001 dodge ram 2500 tail lights not working.

The brake lights dont work when brake pedal is applied also the turn signals dont work. I have changed the bulbs the fuse and changed out the circuit board but it. I have a 2001 dodge ram 2500. 2000 dodge ram 2500 5spd airdog 150 2wd with 378000 miles 90hp injectors and triple gauge pillar pod.

You either have a blown fuse that you have not found a defective combo switch or a broken wire open circuit. I think the problem is between the fuse box and the light switch. I have a 2002 dodge ram 1500. I lost my dash tail and park lights.

My passenger side tail light will not work. I dont care if it says it is for an ejection seat if it looks like a fuse test it. Idk but with out the flasher fuse the brake lights will not work. Suggest testing all the fuses you can find with a test light by touching each side of the fuse on every fuse.
