wmburns SN Certified Technician Aug 14, 2009 5,892 514 204 Houston Texas Apr 8, 2018 #2 Apr 8, 2018 #2 I'm going to assume that the bright lights head light bulbs themselves have been checked and confirmed OK. Just wondering...... Have you checked fuse F2.38? Confirm power in and out of the fuse with the head lights on. Use a known good ground. Does the dash bright indicator (blue light) come on? IF there's no power into F2.38 with the lights on then suspect a problem in the multi-function switch. 1999-2004 MY fuse panel schedule: http://www.allfordmustangs.com/foru...r-swap-wont-fire-please-help.html#post2669271 Last edited: Apr 10, 2018 Reactions: thunder1335
