I went thru all of the fuses replacing them, located under the dashboard, under and to the left of the steering wheel, after replacing the fuse, i belive that it was in the middle row of fuses, my radio, cig, and a/c, heater started working, also that antenna, don't know how long it will work, but it was not working, now it is, with a new fuse. I hope that this helps, i followed the advice from others here, on this site.
