blower quit working on 2003 Dodge Ram 1500

I turned off my air one day and now it won't turn back on. I've checked all fuses, blower resistor,and motor I have no power to motor. Also when i push the button for the air it lights up it never did that before. The ac cooling fan runs all the time now.

To start , when you say A/C cooling fan, do you mean the condensor fan under the hood , or the blower motor inside the truck?(I am aware you say no power to 'motor' just want to clarify --I'm a little slow.
ck blower relay and resister to start with.can you get your a/c module scanned for codes. do you have manual controls or automatic controls?
