New to me, very clean '98 interceptor. All of a sudden the turn signals quit working. Checked the fuse and it is blown. Replaced with new 10 amp fuse, turned ignition, and it immediately blew again. Replaced with 20 amp fuse, same problem. Front running lights continue to work, even after fuse is blown, but they go out when I activate turn signal. Help? I am not a great mechanic and have run out of ideas. Any ideas greatly appreciated.
