Electrical Problems??

[School Boy]

So I got my car up and running and when I first started driving it everything was working properly. Now all of a sudden my auto seat belts do not work, my head lights will not go up or down, the interior lights will not go on (no matter if I open the door/or use the switch), and the light ring on the ignition will not light up any longer. If it makes any difference the battery is relocated to the trunk. I triple checked my grounds. I have 2 grounds coming off the battery in the back, they are both good grounds. Why did all of these things work great when I first started driving the car and now the don't?? Could it be a blown fuse somewhere? Any help would be appreciated!

Yes, that's correct. By grounding that wire, you are basically bypassing the thermo (fan) switch.

Cool. Thanks man! I will give that a shot. Then I will at least know if the ground is the issue.

The the fact that the fan runs when you jump the relay actually tells you that the fan motor circuit is good. You basically just need to figure out why the fan relay is not activating.

I would say it is either the wiring going to the relay, or the thermo switch for the fan. Those are the two most likely causes.

Ok cool. Where does the wiring for te relay go to?

The wiring I'm talking about is the ground wire for the relay coil. It is the blue/black wire I've been referring to. Do the tests I said in my previous post. If the wire integrity is the issue, then trace it from the thermo switch to the relay coil, and find the break.

Cool. Ill give it a try tomorrow.

Did you check the fog light switch, the fuses, or a short somewhere seems like it all went bad at once sounds like a fuse, ground, somewhere down the line. Check fuses in the car and in the engine compartment, anything else not working.
