Help please, electrical system shorting?

I own a 1987 2.3-16 in mint condition. In the last couple of days when the headlight is on, I noticed that whenever I turn the directional on the right, the windshield wiper turns on, it does not do this on the left. It also happens when I turn on the fog lights and when I turn the high beam on. When the fog lights and high beam are on, the wiper automatically turns on. I also noticed that the right side headlight and fog light are dimmer than the left side. I checked the fuses, they seem to be ok. Could the problem be in the headlight switch or the directional stalk.

Has anyone had this happen to them and if someone can help me diagnose it?

Thank you.

Regards,
