electrical haywire

I just ran into the same problem. Everything electrical in my vehicle went haywire for about two weeks. One morning my radio turned on ran down the battery, I’ve been disconnecting the battery every time I stop my vehicle since then. Two mechanics told me that it was because of water that got on the fuse panel and GEM module. Dose anyone know if I really need to replace them both, or if it will be ok after the moisture is gone, and the leak sealed?

you need to reinstall the windshield for the leak - very common on these - and yes replace both parts as a unit
