[Windshield Wipers] Exposed wiring gets wet --> no connectivity?

The wiper motor on my car works when it's dry outside but as the rain comes down, it stops working (when I need it).

The guys at the Indy shop thinks it's the moisture in the air that is compromising the exposed connections to the wiper motor.

The first question is is this a plausible explanation?

If so, can anyone recommend a waterproof version of RTV Clear or similar product that I can apply (preferably via spraying) to the connections that will:

a) seal them from any moisture and
b) still allow electricity to be conducted

Thanks

I think it's unlikely moisture in the air is causing the problem.

Do they work for a while when it first starts raining?

If you walk up to your car when it has been raining but you haven't been driving, do they work for a while or not at all?

What kind of car and what's the mileage?

This kind of rules out just moisture in the air.

It's possible that water is splashing on something when you are driving and causing the problem, but I suspect it's a thermal problem.

Try this: On a dry day, run a hose lightly on the windshield (only) so you are not running the wipers on a dry windscreen. Turn on the wipers and see what happens. I suspect they will run for a short while and then quit.
