Ive seen windshield leaks cause cecu controlled problems. If i remember right the water runs down the harness. I would pop the console out and inspect the plugs on it for moisture. Otherwise i would say possibly key switch issue and nothing to do with the rain. The key switch i believe is monitored by the cecu which in turn turn on the various ecm/systems. If u heard no clicking that would be a sign at least the abs control module wasnt told to shut off, along all the other modules including ecm[/align]. Id start by checking cecu for moisture, and proving key switch is operating properly

Thanks, yes it does have the center console.. I'll get it apart and check it out.. I did however replace the ign switch last year because it was sloppy... but I guess that doesn't mean it couldn't be bad now I suppose.
