This is a subject i have NO experience in. The entire unit has worked just fine since the car was new. All this started last week. If i try and turn the Fan on inside my car(on AC or Heat) on 1,2,or 3, it doesnt do anything. No air is blown what so ever on any mode. On 4 it will blow full blast. With the AC on no cold air is being blown though. On Heat it blows hot. Im checking fuses/relays as we speak but dont think thats going to help. Please respond. It gets a little to hot is Mississippi not to have AC in my DD. Thanks

 

Wow no one?
