Ok. The lights on the buttons to select heater/defrost/high low, etc work, and when I click on the AC the engine bogs. but no fan, no air movement at all at any setting.

Is there an easy way to determine if its the Blower motor that is bad, or the switch. wich is "Most likely" the problem (read wich had the most common breakage)?

Thanks in advance!

Check fuses first. Have any of the fan speeds worked prior? Or has it always not worked? The blower motor resistor should be checked first. The most used fan speed(s) fail first. Once it is out you can see if it is bad. Or just test for 12V to any one of the blower motor pins. If there is no 12V apply 12V to it. It will quickly fire up full blast if good. Assuming you dont have a mouse nest in the heater box. Look into the switch last see if its plugged in...etc. Thats a start.

Fan hasnt worked since I bought the car (Just got it not long ago). Blower motor resistor.... I assume this is going to require removing the blower motor... yes?

this payday Im going to break down and buy a chilton manual. I hate not having a clue.

Nope, just remove the glove box, and it's right there.

I'm just gonna guess: search "heater blower relay" here for your 80% probable problem.

if its the switch on the blower motor it will only work on high. Only postions 1, 2 and 3 go to the switch, 4 goes directly to blower.
