Fog Light Switch Problems of Nissan Titan

Factory headlights have a ballast that controls low beams and day time running lights that is retaining water and causing headlights to either stay on or not work at all. I have had a Nissan dealer look at it and they don't want to do anything about it as we use the truck at night and day and only have high beams. It all started after we bought the truck and washed it the headlights would flicker on and off and the driver side low beam stayed on for 17 hours. Replaced the ballast with a used one and it worked but any time it rained or washed the truck it would stop working and now it is completely out and today 5/26/20 had to replace both battery's due to the headlights be grounded out and drawing power. Replaced both battery's and took the truck down the street to the corner store and came back home and the passenger headlight almost caught fire and filled with condensation from the ballast holding water and had to disconnect the battery's to stop it from pulling power. I have a screen shot from the dealer saying the truck has a 5 year/100k mile basic warranty but Nissan is telling me it only has a 3 year/36k mike warranty and will not cover it as the headlight assembly's are $1200 each plus installation. I have already got a ticket for the lf headlight being out and a ticket for driving with high beams on. Constantly have a error message on my dash and only have fog lights or high beams.
