you should first check the blower motor fuse in your fuse panel. I the fuse is good you might have a bad blower motor. we can check it out for you, give us a call 224-801-6094 Ira Action Auto Services Inc 648 E Northwest Hwy Palatine, IL

If all of those quit working it could be a blown maxi fuse. There are many other things it could be. We would recommend taking it to a certified shop to have it checked out before you just guess and replace parts. Give us a call if you would like us to diagnose and repair it for you, 262-728-2944.
