As far as the headlights have you checked to see if the bulbs are good? I would start by checking the owners manual for the fuse locations. Also check to see if there is a common fuse for the things that do not work. You will have to check the radio and see if it is plugged into the original plug or if someone replaced the radio and just spliced some wires to get it to work. Make sure your battery terminals are clean and tight. The car was not a flood car was it?

yeah im doing that right now but i just found a sensor and other stuff from alarm that somebody did a bad job hooking up that dont work no more under the dash i wonder if this has anything to do with my problem

When someone, that does not know what they are doing, tries to splice in an aftermarket electrical product to a Cadillac will cause all kinds of nightmares. I would say that all your problems are from the botched wiring job. I would take out the alarm and resplice the like wires back together and hope you do not cross something. Fuses are probably blown and will continue to blow until this problem is fixed.

Good work. Post some photos of the corroded parts/relays. We recently discussed corrosion in the relay area, see this thread especially post #18
