I have a 1967 Cutlass. All my lights work except my running lights. Can anyone help. My brake lights work but my tail lights do not. I replaced the head light switch and fuses are good power makes it back to the lights and lights are grounded otherwise brake lights would not work.

 

You mean parking lights?

 

on my 65 the front running lights/turnsignals wont lite with headlites on, only in half/parklite position

 

The parking lights up front don't stay on with the headlights until 68 I believe.

 

That is correct. Prior to the 1968 model year, front parking lights only come on with the headlight switch in the park light position, and go out in the headlights position.

 

If you have power and ground to the tail lights, then aside from bad bulbs or sockets, they should work.

Only the two tail lights are out? How about the dash lights?
