Every now and then after my 00 EB Expy has sat off for a while. I hear a strange noise coming from uder the ood. like a clicking noise that lasts for about 15-20 sec......has anyone ever heard that?

 

sorry thats "under the hood"

 

Mine has a strange hard to describe noise from under the dash about mid way sometimes, especially after it rains. It sorta sounds like a buzzer is tring to go off but doesn't all the way. But mine is obsessed with weird electrical problems anyway. I know about the windshield leak problems causing electrical problems with the GEM, but I cannot find any evidence of water in that area by reaching my hand into that area. I might get the windshield replaced anyway to see if that helps. This probably doesn't help you, but you might note if it happens after a rain.

 

Jrangle, it might be your fan running. Mine does this too after a rain sometimes, just turns on by itself. Try turning the fan to the off position to see if it goes away.
