A small piece of metal from a cell phone charger got lodged temporarily in the cigarette lighter/electrical outlet. It blew the fuse for the radio and the cigarette lighter, but both now work after I replaced the appropriate fuse. Oddly enough, however, the cruise control on the car no longer works nor does the light on the cruise control button next to the dash turn green. Could I have blown another fuse when the other one blew? Which fuses could possibly control the cruise control? I checked the one listed in the manual, which is fine, but are there other fuses involved? Any ideas what might be wrong? Thanks.
