Hi fuddy,

Unplug blower fan motor wire connector and with ignition switch turned ON, test if any of the wires has battery voltage.

If voltage is not present at both the wires, the power supply from underhoood fuse box is getting to the blower motor. It could be a bad fuse, loose wire connectors or a faulty relay.

Sorry for the mistake made in earlier post.

The blower motor relays are underdash.

Ensure battery voltage is available at Blue/White wire when ignition switch is turned to ON. If no voltage is available, check fuse # 37 in underhood fuse box.
