I've had this problem, there was a checklist of things we did. Lights were checked for wiring, then replaced the alternator, and then what finally FIXED this problem for me was putting in a fuse that wasn't originally installed in my car. I have a 99 Cougar. I don't have the exact name of the fuse but check and make sure there are fuses in 4, 7 and 8 in the fuse box. Try this -- maybe this might help someone else actually get the name of the fuse for you Good luck!!
