power door locks sticky. will the locks fail?

I noticed that on my 98 camry, the passenger power locks are a little sticky. they work on both sides of the car but im a little concerned because I think that they are sticky because of a time that someone spilled some soda on the right armrest(nobody eats or drinks in the car anymore). It was at least a month or 2 ago and there have been no lock problems so far. But my question is, should I be worried about the locks shorting out or failing or something? I can live with a sticky passenger power lock button but I dont want all of the locks in the whole car to fail. Is this a concern or am I just being paranoid? thanks.
