I'll start by asking forgiveness for my ignorance but thought I'd ask here first before going to the dealer.
My coolant temerature gauge simply stopped working. Is there a fuse for it???? I looked but couldn't find one.

Is it a sensor that needs to be replaced??
Two other odd things I noticed at the same time are my parking brake light and low fuel light also no longer work. Could they all be related??

It's a very odd coincidence if not ... anyone ever have this happen?? ever heard of it??
Any help/direction greatly appreciated.
Thanks,
Aaron
