F150 tail light

[The_rabbit1]

riddle me this... Right rear tailight works fine in parking light, stop, turn, and flasher mode. Front lights work as should, But left rear Tail only works in turn mode... No parking light, flasher or stop. Let's see if anyone can get the answer. 88 body style.

Check the ground. I have seen a coroded ground keep it from working.

but it flashes fine in turn mode, no power to tail light in other three.

I did figure out all electrical to rear lights go through the turn signal combo switch, so I'm figuring the problem is in it.
