Answer
craig;
        ok  the only thing that i can think of is there might be a leak of some kind that might be letting water in from the windshield or by the wipers etc. and going in the underside of the dash or someplace if you park on a steep hill does it drip or leak annyplace?. That is the only thing that i can think of, all i can say is look for any unpluged holes under the hood that should have a plug in it or get some silicone in a tube and plug up any holes or would be leaks , that is all i can think of now.ok
good luck
p.s. do you have cruse control ? it could be that from vacume if you have it.
