SOURCE: Blower motor won't work.

In there you have four devices to check out to pin point the problem: the switch it's self, the blower relay switch, resistor block, and the blower motor it's self.

I find this information in the Haynes Repair Manual and from another Ford Forum:
Electric diagram shows the blower motor relay in the,
"Blower/Flasher Relay Block". I inquired at another forum regarding the location of referenced block. The response was either in the Power Distribution Box under the hood or part of the Generic Electronic Module (GEM) probably located behind the fuse box at the lower driver side dash.

The blower relay and the flasher relay both share the same block, the flasher is blue and the blower is black, and are the same size. There is a plastic cover (snap on) over them which ia about three inches long and about two inches wide. The block is attached to an "L" shaped bracket, which is attached to the dash support by two screws. The only panel I had to take off was the lower dash panel under the steering wheel. Once the panel is off the bracket is about six inches to the right of the steering wheel braces and four inches left of the cigar lighter. If you take out the two screws on the brace facing you the block will swing down and out. Then you have easy access to the relays.

Good luck
