phillys14 Posted April 25, 2010 Share Posted April 25, 2010 Recently found the passenger side headlight was dim. Upon inspection, found the wiring harness melted (which appears to be a common problem). If I wiggled the harness, the light would get brighter. I replaced the harness with an after market one. Headlight still dim, normal and brights. Bulb is bright in driver side harness, other bulb dim as well when inserted in passenger side. Volts check out ok. My only thought is the wire that melted needs to be taken back further, hopefully not replaced. Any thoughts or suggestions would be greatly appreciated. Thanks.

Olnick Posted April 25, 2010 Share Posted April 25, 2010 When you say you "found the wiring harness melted" do you mean the plastic socket that holds the lamp and fits into the back of the headlight reflector unit? Did the aftermarket replacement come with wire pigtails? Did you match them up properly to the old wiring and make good solder connections?

phillys14 Posted April 25, 2010 Author Share Posted April 25, 2010 Correct, the plastic socket that plugs into the headlight was metled. I double checked and all wires are correct. Don't have the capability to make solder connections, have butt spliced them, but getting good volt reading. The light was dim with the old melted plug, so not sure if it's related to the connections to the new harness. But also not sure where to go from here.

Gloyale Posted April 25, 2010 Share Posted April 25, 2010 The fuse for that bulb is blown. Headlight is lighting via a power backfeed from the other side. caracterisic of these cars lighting systems. Replace the fuse for that side and it will be bright again. Quote Link to comment Share on other sites More sharing options...
