Daytime Running Lights

I have bulbs, as the low beams and DRL, did not work that did not solve the problem.
I also saw a video on YouTube about this and you are right it is corroded at the connector under the battery.
Mine is a 2000 Cavalier and I would not say the connector is under the battery tray, but more along the side of it, also the connector box looks different more round, but there is a hole in the connector box.
