I was wondering is there a fuse diagram for the 2003 Ford Explorer XLT? What causes the left and right signal lights to not work on the 2003 Ford Explorer XLT? Can the side mirrors on the 2003 Ford Explorer XLT?
change the bulb .also check for bad ground on that light
Try replacing the turn signal assembly. Everything is built into it.
Your flasher relay is defective, replace it. See sources and related links for bulb information.
There are a couple of reasons why the turn signals will not work on a 1998 Ford Explorer. The light bulbs may need replaced or a fuse has blown.
lites while breaking but not as turn signal possibly a single eliment/filiment/action bulb ... wrong bulb
it could be a bad relay
You could have a lose wire in the stering column.
Check fuse and turn signal flasher relay.
I have a 2001 ford explorer that was doing the samething. The trouble started when the ouside temperature got cold. I replaced the flasher unit and have not had a problem since.
