I have a 2008 Ford Fusion SEL 3.0L V6. 5 days ago my Left Rear Turn Signal went out. I noticed this because my blinker was flashing rapidly and on the dash display said to check LR Turn Lamp. Now today my Right Rear Turn Signal started doing the same thing. I decided it was time to try to fix the issue. I checked the exterior light fuses and nothing was blown. I bought 2 replacement bulbs, but my rear turn signals still were not working after being replaced. In the process of seeing if the new bulbs worked I noticed that my brake lights were not operating as well. My 3rd brake light in the rear window works though. Also when I turn my hazard lights on the two back hazards are not working. But when I turn my head lights on the rear lights that share the brake light bulbs get power. Just to be on the safe side I checked all of the fuses in my SJB below the steering column and everything was OK. I went ahead and replaced my brake light switch above the break petal and still nothing. I have a repair guide for my Fusion and found that the wires coming from the SJB to the Rear Turn/Stop/Park lights are the Violet/Orange and Grey/Brown. I checked the wires in the trunk and everything looked fine and also checked the wires on the connector going into the SJB and everything appeared fine. I couldn't get a real good look at the wires on the SJB side being that they are behind the dash. I found that my contortion skills, trying to get a good look at the connectors and wires on the SJB side, were not the best.

At this point I am thinking it is a wiring issue or a SJB issue. Any help on solving this crazy issue is much appreciated. My troubleshooting steps are below in a easier format to read.

Check wires leading from smart junction box in pic if no power there with brake applied then you'll have to have it scanned to see if sjb is bad as it's a module.
