Turn signal and brake light

[jmc1975]

I have a 1970 f100 custom the right front turn signal does not work and the left rear turn signal does not work, but the left front and the right rear work. All four parking lights work, any idea on how to fix the problem?

it could be many things such as
the wrong bulbs
a bad socket
bad wires
bad tss.
on the rear light does the brake light work? if it does you can rule out wrong bulb and or bad socket and wires from the firewall back. sincce the turn and brake light use the same element

the right rear brake light works but not the left

[fordman]

ok check the bulb the socket and everything else up the line.

Hey thanks for the help I located the problem in the turn signal switch. Everything is working as it should now.
