I replaced the blower motor and the blower resistor and they work fine, but the air only comes out of the defrost vents now. I think the air diverter actuator is bad. Where is it located and how do I replace it?

You could have a vacuum line that has broken near the firewall or just inside where the heater plenum is. Here is a guide to help you see what to look for. I should have the actuators locations by tomorrow but check this first.
