I have a 09 Scion Tc that recently stopped blowing any air when the a/c is on or off. I immediately thought that it was the blower motor as I have not replaced that, and the car is getting older. After removing the blower motor and installing the new one nothing changed, I still had no air blowing. My next thought was that it must be a fuse or relay. The a/c fuses (and all other fuses as well because heck when in Rome) were fine, I then replaced the a/c blower motor relay and still nothing blowing. I also checked to make sure my a/c system had enough r134a which it did. Can anyone help provide me with some guidance as to what else may be going on?
