Intermittently, I would lose brake/LH turn light on my boat trailers. A shot of good ol' WD40 would restore function.
Today I decided to get serious. I hit each connector pin on the truck side connector with some red De-Oxit contact cleaner. I swabbed out each pin with a cotton swab. The swabs came out nasty coal black.
I would say there was some corrosion and grime in there.
Time will tell how long this "fix" will last. I've had a lot of good luck with De-Oxit on low voltage connections in the past though. What I like about it is that it cleans, protects and lubes electrical contacts.
