AC/heat fan blower not working

It sounds like one of two things has happened either you have a blower motor that is out or the fuse is out. We must check for power at the blower motor and fuse to determine which. Here are two guides and some blower motor wiring diagrams so we can get the problem fixed.

Please run some tests and get back to us.
