I'm a novice, so bear with me! My radio and heater lights are out, as well as both tail lights / parking lights. The brake lights still work. I tried changing the upper tail lights but no change. I checked the fuse box under the hood but couldn't find anything tripped (it's possible I missed it, though). Any suggestions? I'm in kindergarten when it comes to vehicle maintenance so please dumb it down for me. It's a 2007 Tacoma Pre Runner SR5.
