Turn signel problem

At the front I changed the leads back and forth, and tried a different bulb wiithout success.

I then went back to the steering column and switched the wires to change sides. The Driver side front turn signal continued to work but the Pass side still did not work.

Then by trial and error I determined the green wire on the Pass front parking light is the power for the turn signal filiment and I traced it through the diagrams back to under the dash. As a test I hooked up a test light and stabbed both sides of the fuse holder under the steering column with the green wire and the turn signals on. The light in the dash was flashing but my test light never flashed. I then put the turn signals on for the Driver side and the test light flashed with the turn signals. The fuses look fine and there doesn't seem to be power to either side.

Apparently I'm not getting power to that fuse holder and I suspect that it comes from the turn signal switch (haven't traced that out on the wiring diagrahm yet.

I'm suspecting the turn signal switch. Thoughts? Suggestions for further testing.

If the rear signals work, it's not the signal switch.
The fuses under the dash are strictly for the rear lights. They are there because the trailer relay is really sensitive to a momentary short, and some people were accidentally blowing it up when testing connections.

So...
First, check the several multi-pin connections from the trailer relay board to the dash harness. Sometimes a pin isn't all the way in. Pay special attention to the green wire connections.

If OK:
Turn the parking lights on. (Ignition off)
Is the passenger's side parking light on? Is it the same brightness as the driver's side?
If so, disconnect the green and red wire on the right front parking light. (The red wire is still live.)
Touch the live red harness wire to the each of the leads from the parking light. What happens?
