Door lock horn after wash doesn't work

[kutzenshlagen]

So I washed my truck this afternoon like usual and when I went to lock it this evening the horn the chirps when the doors lock is very very muffled and sounds like it is failing. The truck still goes into full alarm and the steering wheel horn sounds okay (I think), but the door lock horn definitely doesn't sound right.

 

Are there two horns on the 900? Water in the relay/horn?

 

Thanks for the help!
