Volvos have a resistor module for the low beam lamps that plugs into one of the fuse/relay panels, and the connection between the two is a notorious spot for corrosion. Last year, the headlights went out, and the fault was that very joint. After ordering a new module, I discovered that the original worked just fine after cleaning the contacts, but now it's gone out again. I know there is also some corrosion on the contacts inside the fuse panel (which I don't want to replace-$$$). I think I used deoxit last year, but I'm thinking there might be a better electrically compatible corrosion inhibitor for automotive applications; maybe a gel of some kind? I don't want to use anything that's even remotely conductive.
Suggestions?
