Check your transistor and plug. It may have come loose. It has 4 wires going to it and is under the dash on the pass side.

It sounds like your relay could be bad. When your relay contacts become worn your volt meter will show 12v coming out of the relay until you put a load on the circuit, then the power goes away. You have to get to the wire going to your blower either from the back of the relay or by sticking a straight pin through the hot wire. Clip your + lead to the pin and the - to a ground. Turn blower switch on. With the blower unplugged you will show 12v but when you plug in the blower the power will disappear. If this is the case your relay is bad.

Start simple and check the fuse. If you can run the fan on certain speeds but not others, it is most likely the resistor. If the fuse is good but it wont run on any speeds, look at the relay (this component is first in the circuit. If all components turn out to be fine, look lastly to your blower speed control knob.

Most likely either the controls are bad or the blower motor resistor. To check you can see if the controls are getting power and if they are sending power to the blower motor. This will tell you if the controls are bad or not.
