Hi,

Do you mean the blower motor isn't turning on? If that is the case, the motor itself may have failed, there could be a relay or resister issue, or the switch may have failed.

Do me a favor. Check the 30-amp blower motor fuse in the under-hood fuse box. When checking it, make sure it's good and make sure there is power to and from it.

Here is a link you may find helpful:

I attached the schematic below showing the blower motor fuse. Pic 2 shows the fuse location in the under-hood fuse box.

Let me know what you find and if it is the blower motor that isn't working.

Take care,

Joe
