Hi 2003 Trailblazer I have had some problems with headlight coming on then just going off randomly - now I can only use headlight on high. the rpm gauge has not worked in a long time, today gas gauge is all over the place only 86,000 miles i checked fuses could not tell if they were bad.

I'm not even trying to be mean, but if you can't tell the difference between a good fuse and a blown one you need to drive over to a good shop and let them take care of this for you. As it is, you need a high-end scan tool that can access the body control module of this and has the capability of bi-directional control for testing purposes. The one I have that can do that cost me $4000. Their bill bill be much cheaper.
