69 mustang
No left turn signal
No brake lights either side

Everything seems to be connected and grounded.

Brake light switch jumped 12 volts in 12 volts out no lights

Consulting the wiring diagram it appears that circuit also runs through the turn signal switch. I am wonder if that could be the problem? What else should I check? The switch is not that old

What do you guys think.
Thanks in advance

bad dirty bulbs/sockets, ground missing or loose/corroded, shorted wire from switch to bulb sockets. Do continuity test from the brake light out wire to the bulb sockets to see if the wires still good

Thanks, car has been completely rewired so all sockets are new. But I will as you suggested.
