Hi, I need help.
My headlight low beam bulb was out, so I changed the bulb, it did not work, so I took off the bumper removed the headlight and I thought cleaning everything should be fine. So I removed noticed corrosion on
Circuit board. I cleaned it with a cleaner(contact cleaner) and I also cleaned the module with that cleaner. I wanted for them to dry and then put them back on replaced the light. When I tried to turn the light on nothing comes on on that side only got light. I don’t know what I did wrong.

I know that the module is bad since it was corroded. But lights at least worked.

I had adaptive light malfunction message before. Now in the error window
It lists all the bulbs not working.

This happens only on passenger side light. Driver side works fine.
I really need help to figure out what went wrong. Do I need to reset something.

Thank you.

I had the same issue. I was getting water splashing onto that circuit board which is for the halos and it was causing a lot of corrosion. I replaced it and also pulled the headlight and cleaned all of the plugs and connector put it all back and it's been fine since. I don't know if I'd get the module wet enough to where it has to dry. That could be a bad things in my opinion.

Only thing works now is halo lights, nothing else works on that light. I tried one from Amazon, it did not work.
Where did you get the module from?
