So the other day I noticed the fan was making a ton of noise.. I just leave it on vent all the time.. Well i went to defrost the windows and now it won't leave the defrost..

Earlier in the summer when I would hit the AC button it would stick on and have a hell of a time coming off.. sometimes the AC system wouldnt got off until i shut the car on and off again a bunch of times..


2nd lame question.. and I will probably feel like an Idiot for asking this.. but underneath the dash in front of the gas pedal is a green light that flashes when the door is open.. but there is a switch in the back.. what is that thing for?
