Okay so the new fuse is in, the dome light works and all the lights and signals work. But once again when I press on the brake pedal only the left brake light works, and it turns out that all the flashers work but the right tail lights as well. Bulbs are fine, I checked again. I'm pretty sure the problem is in the signal light switch, because only had this problem after I changed it out. Could it be a faulty switch?
