I'm truly stumped

[92470]

I posted an earlier thread with this problem, but now my problem has changed a bit. I have an 87' V10 with dual headlamps. I had a issue with when I turned my high beams on, and then the right turn signal, the right parking lamp, turn signal, and high beam would not work. The right turn signal indicator would also light up green, but not blink. No highbeams, you had no problems, but the turn signal blinks slowly and you could see the lower lamp barely glowing and also blinking!

I have checked and cleaned all the grounds, the harness, cleaned all the connections, checked bulbs, still same problem.

I was ready to give up because I couldn't pin the problem down, but then something happened. Working on it in the garage, I turned the highbeams on, and then turned the key on to try the turn signals. When I turned the right turn signal on, the seat belt warning tone started to buzz faintly, and I could hear the fuel pump relay kick on! I jiggled the turn signal right again, and the fuel pump relay buzzed again.

So, I know it is in the dash now. It has to be related to the ignition somehow because when the ignition is turned on, it normally activates the buzzer and kicks the fuel relay on. So what in the heck can it be? Turn signal switch, dimmer switch , turn signal lever, ignition switch? How would the highbeams, turn signal, and ignition all connect?

Sorry for the long post, but wanted to get all the facts in. Any direction is appreciated. I hate trouble shooting by throwing parts at something. I'm going to pull the column panel off and see what I can find tomorrow. Hopefully something will be evident. Probably not, but...!! Thanks
