Hey guys, I just wanted to see if anyone was having any similar type problems. I just bought my 91 240 coupe a week ago. It's got it's issues but it runs and I love it. A main issue I'm having is driving at night. Only one headlight works. Only The drivers side low beam works and if I switch to high beams the passenger side only works. I started off by replacing the bulb but nothing changed. I checked the fuses and none were blown so then I started digging deeper. I hooked up a multimeter and checked the voltage in my headlights. The drivers side low beam has 12 volts where as the passenger side is only receiving 10. If I switch on the high beams its the exact opposite. Passenger high gets 12 volts and driver high gets 10. At this point I'm lost. Why would it get some power but not enough to get the bulb on. I haven't gotten deeper in yet and chased the wires but I really don't want to unless I have to. And I don't want to pay $80usd for a new headlight switch. Any ideas? Thanks in advance!
