It could be that. What has happened is the windshield will leak a slight bit and drip water on to the GEM. As a result, problems start.
THe GEM (I believe) is mounted on the top of the fuse box under the dash in your vehicle. Check it for evidence of water getting to it. As far as I know, that is the only cause of them going out.
Let me know what you find.
