My radiator broke so I just got it fixed and putting it back I noticed it won't start the headlight won't work the signal lights won't work and the rear signal lights stay on all the time...there is a fuse under the passenger seat when I remove it and put it back in it will start but the next time it won't any Idea's

 

Check your front wire harness for bad wires. Even a little burn on the outer casing should be dealt with. Also make sure all connectors are firmly together with their correct plug. (Usually easy to tell) if any fuses pop it's usually a short or a possible incomplete circut. (Pull a tail light bulb and turn on the ignition. It will blow the fuse for the rear because the incomplete circut will not have the resistance from the second bulb.this is the same with the front as well. Hope I helped. I figured this out the hard way.

 

How did the radiator break?
