Here is another post from Renn.
Can anyone help me translate this into directions for a n00b ?
Which is the positive terminal on the relay? Does he mean fuse?

You need a volt meter.
Turn ingnition switch to all the way on, but do not start the car. Then turn your auto heat dial (between the seats) to any on position. Make sure the lever moves upward a bit.
Go to the relay with the volt meter. Touch your negative lead to the metal surrounding the rely. Touch the positive lead to the positive terminal on the relay. (if memory serves this is the 3rd fuse). If your needle moves you have juice to the rely.
Now, on the right side of the blower motor there is the wire connector to the blower. Unplug the connector. Touch the leads to the separate points on the connector. Switch leads to make sure you have pos/neg right. If needle moves on either way the relay works and the fan is shot.
Hope this helps. This is what I did to determine that my relay was fine and the fan was kaput.
