My 2002 FX4 is constantly draining my battery overnight. But the catch is that it does not do this everyday. It seems to do it when it is wet and cold outside. Ford said there was nothing wrong but I never believe those guys anyways. If anyone can help it would be much appreciated.

 

do you have anything aftermarket installed? overhead MV or anything at all?

 

I have new corner lenses on it now but the problem started long before I put them on.
