So basically water got into my mother’s taillight from a bad seal, and corroded one of the bulb holders.
It had no power anymore whatsoever.
So I cleaned it with a wire brush, soap & warm water, bicarbonate & white vinegar, then I dried it with a hairdryer and sprayed it with electrical cleaner.
Then I plugged it back in and everything was working again.
I decided to check the other taillight and I noticed that it was full of white rust much like the first one was.
So I decided to clean this one up with the same method.
I plug it back in and now the indicator & fog light will not work.
Can I do anything to fix this? Or have I obviously shorted it or something?
I don’t know that’s behind the black bit in the centre but does it contain something that I may have shorted out? I admittedly didn’t dry the 2nd one for as long although it did look & feel dry
