Weird list of issues that happen at the same time

I have a 2004 TL and i am having some random issue and wanted to know if anyone can shed some light. All these things below quit working randomly but all at the same time:

no keyless entry
no high beams
wipers only work on super fast mode
outside temp reads --

any ideas on what would cause these things to happen?

The TSBs can be found by clicking on the sticky link at the top of the "Problems" forum.
