hello all. this one's got me stumped. my low beams on my 1986 760 turbo wagon work fine on both the driver and passenger sides. However, when i turn the high beams on, the passenger-side lamps work fine (both very bright), but the low beam and high beam lamps on the driver-side go extremely dim. i just replaced both lamps, so i know that is not the problem. any ideas???

the tail lamps are also acting funny. driver-side blinker works fine, but when i switch on the passenger-side blinker, the yellow blinker clicks on and off as expected, but is joined in alternating style by the white section of the driver-side tail light. also, when the passenger-side turn signal is on, the white and red sections above it on the same side light up slightly and blink in time. i'm not sure if this and my headlight issue are interrelated.

i'm baffled here. very little experience with this type of electrical stuff, so any help would be GREATLY appreciated!!!

thanks in advance, aa
