I have a 67 Chevelle that I am having a problem with the passenger side turn signals (front and rear). The turn signals work perfectly fine until I step on the brake petal. The lights go from blinking to a stopped signal. It seems as though the stop light signal is overriding the turn signal. Drivers side works fine. The signals work fine with the driving lights on or off. It's just that the passenger side doesn't want to work properly with the stop and turn signal engaged.
Any advice is greatly appreciated. Thanks in advance.

Yes the brake will try to over-ride it because the brake and the turn signal share the same light bulb filament.
Try this:
Remove the right rear bulb and socket. Leave the bulb in the socket.
Touch a piece of wire to the metal bulb base, right where it meets the glass.
Touch the other end of the wire to a known clean spot on the frame (ground).
Have someone step on the brake and turn on the right turn signal.
Believe it should work right as long as you hold the jumper wire.
If that does it, it's either a bad ground on the socket wire (try to clean that up) or a bad ground wire crimp joint at the socket (replace the socket).
