The blower motor is in the passenger rear of the engine compartment. along with the blower motor regulator either of which may have failed. The blower motor has its own fuse hopefully your owner's manual or fuse box cover identifies which fuse is which. There is a fuse box in the driver's rear of the engine compartment, and one in the trunk not sure if there is one under the dash.
