I have a 16' Lariat Crew cab with the keypad entry system. After a good rain storm today the keypad won't work. The buttons don't light up however flicker when looking at it in the dark. The code does not work either. Has anyone else had this issue? I will be contacting my local FORD store in the morning. Not happy, as my truck is 3 months old with only 4,000 miles on it
