Was driving on the road yesterday and both my headlights (new I bought and installed them 2 weeks ago) cut out and I had to high beam it on home. Also my radiator fan stopped working as well a few weeks. Now with the radiator fan it doesn't start with the engine I have a switch under the dashboard that clicks on. I know the switch still works because when I turn the battery on and try to connect the wires to the switch it sparks....and the fan connection is still hooked up. perhaps the fan motor went out? I don't know...not good with electrical things.

 

if its headlights and a fan I know they ground in the same spot. Try there first and clean up the ground and see if that resolves the issue
