I have a 2007 mustang gt, the gear shifter will not move out of park unless I use the override switch, the driver side taillight will not turn on (turn signal won’t work either, just no power going to it at all), and the passenger side headlight won’t work either, I checked the fuses they all work, changed the bulbs out and still won’t work, also replaced the brake light switch nothing worked, pulled apart the wiring harness that connects to the fuse box couldn’t find anything burnt or out of place Also all three things happened at the same time.

Hi I have the same problem did u figure it out?

 

there are two fuse boxes, make sure you check both of them, locations are in the manual

other than that, it's probably out of my league

 

Water intrusion/corrosion in the SJB would be my guess if it wasn't a fuse.

 

 

I guess I need to take it off and clean the connections any suggestions on what to clean them with? By the way thanks for replies

 

try some searches for "SJB" or "SJB water" or "system junction box water" and you can probably find the other threads with the details of this issue
