What year car? I will look at the schematics and see if I see anything obvious.

Check all the grounds at the body connection points. It looks like you need to trace the right side wiring as not much works over there. I will look at the schematics the lighting is probably almost the same for all years.

If I remember correctly, both front and rear harnesses feed from the driver's side to the passenger side, so you can trace the wires as well to look for any breaks.

I would agree that checking the grounds would be the first step.

Try this with key off, put on right turn signal- markers lights should light on
the right side. Front and rear. If no light on right front check fuse #6 with a volt meter voltage should be present!! If there is the most likely problem is your ground on the right side' Take off all the Brown wires and clean the connectors
and reattach them and see if they work now.

Thanks. Good info. Also bought a turn signal relay to install tomorrow. Since all of the right side is dead it must go to one central ground spot. Adjusting valves today so I cleaned the ground strap good at the trunk, what about the top of the tranny? Does it need to come off and be cleaned too? Let you know after a day of brown wire cleaning.
?? does electrical contact cleaner suffffiiiice or do I need to sandpaper the connections? Or both? Bill

I use some fine sandpaper on a dremel to make sure the both the ground ring and the post are clean for a good ground.

When you finish the valves, I can help track the electrical down. Just let me know when you want some help.
