Running lights on 1991 acura integra dont work

Did you change your dimmer switch? When my rear lights and dash lights stopped working the fuse was blown, but the transistor inside the dimmer switch (just left of your steering wheel) was blown also. (had my dad check it with the multimeter). You'll need a narrow flat head screw driver to pry it out, start at the bottom, that's where the metal clip that holds it in is. Cost me $5 at the junk yard. Hope this solves your problem, annoying isn't it to not be able to drive at night.
