Odd lighting malfunctions

[Milesdodge]

On my project 67 Coronet I’ve managed to get most lamps functioning, but a couple of things are catching me out.
Rear lights and turn signals, brake lights all good.
Front sides/turn signals have opposite functions: drivers side, side lamp works, turn signal not.
Passenger side is opposite, turn signal good, side lamp bad.
Headlamps, both work correctly on dip beam
On full beam the drivers side inside beam comes on, however, passenger side the dip beam stays on. I’m a little confused as to what is causing this. Floor dip switch is new.
All bulbs/lamps are new.

Any weird electrical problem check the ground. Bad grounds can cause really strange things to happen.

Thanks, is it likely that a bulb holder can have a live to one terminal, turn signal works, but marker terminal on same bulb doesn’t?
