Default 2007 Mustang Premium GT Brake Lights

My 2007 brake lights are being a problem.
On the left side 2 out of the 3 lights don't work. I have replaced the bulbs, still don't work. I've swapped over bulb within the 3 and its only light #1 that works, regardless of which bulb i use.

1 2 3
1 3 2
2 3 1
Numbers are the bulb, red - not working, green working.

Could it be the fuse(s)? if so where are they? which one do I look for?
Could it be the turn signal? if so, where do I start?

Please help

I have seen several 05 thru 09 Mustangs with at least one or more tail lights out. Check the sockets for defects or burn damage. You also might get a test light that can trace the wire by piercing the insulation to find where the voltage drops out.

check for voltages at the individual sockets to see if they are getting power. if not, could be corrosion on the connector at the SJB (smart junction box) its located on pass side kickpanel. the tail lights run thru there, as do most other body controls. if it gets wet (known issue) it caused all kinds of electrical issues. you can get to most the connectors with it bolted to the car, unplug and check for corrosion. you can also search "cleaning SJB"... etc. good luck
