Blower controls will not work on any setting!!!!

did you check the relay? also when you say wont work, no power? if so you may have to install a new wiring harness, or go to a yard and get a new control panel and install it into your car, or also check your resister for sppeds if thats what is not working. costs are variable, if its the switch and you go used around 5-20 dollars, a new wiring harness check around at diff shops, resister are also variable from shop to shop
