I have a 95 Suburban. My dash lights went out, I thought no biggie it's a fuse, No way and to top it off I don't have tail lights either. Brake and turn signals work fine, and if my boat trailer lights are hooked up, when you step on the brake pedal the dash and all interior lights come on. I have been pulling my boat for 4 years with no electrical problems. Any help would be great!
