Rather than checking power to the switch and the blower motor, check power to the fuses. If none see if you are getting 12 volts from the white-green wire from your alternator. This is the wire that passes through the starter relay and triggers the AC/heater relay. The reason it passes thru the starter relay is to turn it off when you are cranking the vehicle.
You could also jumper 12 volts to that wire and see if you get power to the ac & blower fuses.

We had checked the circuit on both sides of the fuse box and it was dead (no power) I have replaced the relay already and even switched them around as they are all the same in there and it made no difference. I have read somewhere that someone actually cut the green/white wire and everything started working. I have yet to locate the blower resistor and check it out. That is something planned for this weekend. Working till almost dark and it being in the 30's after dark puts a hamper on auto repair.
What Diagram are you looking at, is it from the Manuals posted on RapidShare? If so can you tell me the page number?
Thanks for the replies BTW I was beginning to think there was no help to be found here.
