You do have what they call a GEM module. It is mounted under the dash against the firewall. It controls all the lighting and time delay features for the power accessories. What usually happens is the windshield gets a small leak, and the water runs down right on this module, making it do all sort sorts of funny things. The water also can corrode your fuse box.
See if your floorboard is wet after a rain and if there is any sign of water on the firewall under the dash area on the driver's side.
