Headlights work, Front parking lights work, brake lights work........

Tailights do NOT work. Other than fuse, stalk swtich to check, any other area ? Where is the "multiplexer" I read on another post ?

 

Try checking the actual bulb and ground wire, it could be too rusty and need replacing.

 

When you said brake lights work, do you just mean the third higher up light or all 5 of the brake lights work? The rear bulbs are dual filaments and I would think if the brake lights work the tail should also. I would think the contact on the bulbs could be rusted, try cleaning them.

 

All brakes lights including the 3rd brake light are working (inlcudiung dash lights). Brake circuit is separate. I have to find the common ground (in trunk area ?) as this is shared by all rear tail / license. Front parking lights on a separate ground and they work (confirms combo swtich OK).

They seen to come on intermittently.
