I have a 97 wrangler Sahara 4.0. All of a sudden the blinkers, windshield wipers and radio quit working. I checked the fuse panel with a light tester and there is no power getting to these fuses in the fuse panel behind the glove box. All the rest of them get power. Could this be a relay? If so where would I find it? I noticed there are many of them throughout the dash panels.
