go to a service shop and let them measure the pressure of the r134 gas, chances are that you have a leak and you're out of gas in the a/c system. The blower motor switch has 2 sides you can turn, left is with a/c and right without. Also if the vents are in the "defog" position, the a/c automaticly switches on, try to avoid this.

+1 That happens when you have low pressure, or now gas at all.
