i cleaned my engine bay a while ago. when i turned my engine on to evaporate the water, i noticed the radiator fan didnt turn on. so after everything dried off, i took the car out and drove for 20 mins, and looked in the engine again and the fan still wasnt turning. i never noticed when my fan would turn on or off before. is it normal not to turn on, or did i f*k something up in my engine.

thanks
