You need to diagnose it a little bit, then get back to us. On the blower motor and resistor. What one is loosing ground or power. It will be either a loss or you will have one doing the opposite of what it's supposed to do. I don't think it would be the switch but it could be. You need to test for power and ground and see what is going on with it so we can tell you how to fix it.
