I am tracing some serious electrical issues that I can't resolve.

86 190D. The passenger turn signal glows constantly. As does the pass turn signal indicator in the cluster. Wiper runs constantly in setting "2" (low speed constant). All lower left side dash lights illuminated constantly, even when key removed. Right turn signal indicator illuminates even when key removed. Tach doesn't work.

Installed new fuses and new hazard switch. I have changed the ovp and the klima for known good units. Replaced the combination switch. Replaced the front turn signal bulb holders. Replaced the rear light units.

Wiper will stop if I pull fuse 20.

Headlight switch? Hazard switch wiring? Ignition switch?

Any ideas?

I had allot of strange problems with my 91 190e. Turned out to be a faulty fuse block. Inside the fuse block the connections are layered and seperated with plastic all molded together. Water had got in over the years and shorted circuits out. I found a good one on ebay. Not an easy job, half the fuse block goes through the fire wall.
