We have had this problem about 3 months. The ac blower wont blow at different times. When it does blow it blows as hard and cold as it should be, however random times when we get in the car and turn the ac or heater on nothing blows out. Occasionally when driving it will just come on but usually if when you turn the car on and its not blowing it wont. We have noticed in the morning it almost always comes on especially now that its colder. However today after it blowing fine all morning when I got in the car and turned the ac on nothing happens, its about 80 today here. Yesterday it blew fine and cold all day and this morning the heat blew perfectly. Anyone have this issue, doesn't seem like the blower motor is out since it clearly works when it does run. Maybe a fuse or something in electrical that keeps shorting?
