Front/Rear Side Markers and License plate light not working
Hi I'm new to the forums and need help with an issue with my project s197. The Front Side Markers and Rear markers as well as the license lights have refused to work. They are not blown as I replaced and still refuse to work. Can anyone tell me what is the potential problem? Thanks

Welcome to CMOC and Happy New Year. Sorry I can't help with your problem, but could it be a fuse?
|
Fuse or a ground wire maybe? I'm no expert, but welcome.
|
The first place to look is the fuse box in the engine compartment. I have a Ford service manual here for an '06. It may vary a bit from year to year, but my '07 car matches what the '06 manual says. With that in mind, pop the top off the fuse box, and flip it over. There is a diagram there with fuse numbers. You want to pull fuse number 63 and check it. This fuse supplies power in part to the SJB (smart junction box, iirc) inside the car. Let us know what you find.
You mentioned changing bulbs...any chance you put LEDs in it? Oh, and welcome to the site. |
I would check fuses first but if a fuse is blown, you have another problem to chase down. Fuses don't just blow, something has to cause it.
|
From what I seen in the manual there is no fuse mentioned. Also something called a smart junction box replaced the traditional under dash fuse box. So yeah no luck there either.
|
No I haven't installed LED's yet, I will in the future as my explorer is fully LED/HID equipped. I have an 06 as well, the manual is useless, nothing about lights and goes on about a sjb that replaced the traditional sjb. I heard the s550 and coyotes dropped this sjb and went traditional. I wonder why.... hmm fuse 63 I will check that out tonight I guess and get back to you.
|
Yeah and that's what I'm worried about, I don't need an electrical problem -___- I already have a slipping clutch a bit of body rust and truck latch problems oh and rear speakers in shaker 500 system has gone bad. Weirdly enough my belt isn't attached to my a/c compressor as well. Oh well it's a project I guess for a reason lol
|
No luck with fuse it's good. Bulbs and fuses are good so what could it be....
|
It may very well be a broken power or ground wire to all those lights. :dunno
|
Nope the wiring is good as well. I did everything mentioned. My mechanic I have for things like this couldn't figure it out either back in November.
|
It has to be in the wiring, what do you think powers them? There has to be a broken connection some where.
Search this site, it has all the service manuals in pdf form. This pdf is for the Parking lights and others. Ford Service Manuals - DIAGNOSIS AND TESTING, Rear and License Plate Lamps.pdf |
This may require a trip to a Ford dealer, and the use of their magical scanner. If the fuse is ok, there is a good chance it is a problem with the SJB.
|
I know wires power them obviously. But I checked the front ones and wires are fine. The rear I will check tonight. I'm fustrated as I know how to fix electrical....only when I can locate the problem. Why is it only my Mustang that is having this problem. Oh thanks for the wiring diagrams btw
|
Ugh SJB replacement is way to expensive so I hoping to avoid that. It's funny because 10-14 and the new S550 use the traditional fuse box from what I heard...I wonder why
|
SJB woes are not that un-common on s197 cars. When they act up, al sorts of weird stuff can happen. s197 Mustangs also had water intrusion issues (particularly the '05-'06 models) that could cause electrical gremlins.
Google s197 sjb, or water intrusion, and the results should give you a bit of reading...maybe even a few ideas on other things to check. |
