Blower motor inop on 2004 ford crown vic

I looked at info for automatic hvac. I'd check for applicable hvac trouble codes, if there are any. Some of the national brand autostores will check po codes not sure about manufacturer specific codes?
Note the diagram for front blower motor, those two wires should be voltage and ground, use a test light to check. Could be problem with blower motor, itself?

The noise can mean several things. It could be a bearing noise or something worked its way into the ductwork and jammed the motor. Without this noise, Ford products had problems with the blower motor resistor and that would be another prime candidate for failure.
You can take the blower motor out and have it benchchecked for electric problems.

The intent of this bulletin is to provide technicians information regarding the proper installation of the Heating, Ventilation and Air Conditioning (HVAC) Module blower motor (with impeller) assembly.

The current available HVAC Module blower motor for the above listed vehicles can be identified by the three mounting holes (1). The original equipment blower motor had five mounting holes.

In order to avoid confusion and ensure a high level of customer satisfaction, when replacing an HVAC Module blower motor, refer to this bulletin for the appropriate procedure.

Eldorado/Seville-HVAC Blower Motor
Caution: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures.

2. Remove the camshaft cover.

3. Remove the blower motor.

^ Disconnect connector from the blower motor.

Installation Procedure
1. If present, remove the 2 ribs located on the barrier. Refer to Step 3 and the illustrations in the Instruction Sheet, P/N 52494110, found in the blower motor kit.

Important: Ensure the blower motor gasket makes a complete seal around the blower motor.

2. Install the new blower motor with heat shield. Refer to Steps 4 and 5 in the Instruction Sheet, P/N 52494110, found in the blower motor kit.
