So recently I went to go unlock my car and the interior lights would usually flash twice but I did it and they flashed once and then shut off really quickly. So later on the night I got home from my drive and went to go lock my car but noticed nothing was happening then I went to go close my sunroof nothing and today I just realized that my radiator fan isn’t working nor are my fog lights. I really don’t know what this could be

 

first off, start checking related fuses to stuff that isn't working.

 

Also test your battery. If your alternator has died, the car will be running off battery which only lasts so long without charging.
