Question about Ford Cars & Trucks
Assuming the fan blower is working, and you are getting heat somewhere, there is a component in the HVAC system called the mode door that determines where the heated air is ducted in your car (some cars have a separate door just for the defrost). It could be the mode/defrost door itself is broken, or it may be the actuator for that door, or it may be the HVAC control unit. If all this sounds like gobbledygook, take it to a qualified shop for repair.

SOURCE: My front defroster doesn't work
Their is a vacuum actuated valve that redirects the flow of air from the panel to the defrost vents when the defrost is selected. I would check the vacuum line running to the valve while the vehicle is running with the defroster on and check whether or not the line is pulling a vacuum to actuate the valve, if not you obviously have a bad line or vacuum line fitting. If you have suction on the vacuum you will need to check the valve and see that is functioning properly. The valve is usually located under the dash on the passengers side. If you are mechanically inclined i would go to a local auto part store and pick up a repair manual for your car for about $20 as they contain diagrams and info that will save you alot of money.

the deflecter is not working you were probably using the defroster when it quit working you will have to take the dash out in order to replace it with a new one.

P1237 - Fuel Pump Secondary Circuit Malfunction
Electronic Returnless Fuel Systems (ERFS) utilize a Fuel Pump Driver Module (FPDM) to control fuel pressure. The PCM uses a Fuel Rail Pressure Sensor (FRP) for feedback. The PCM outputs a duty cycle to the FPDM to maintain the desired fuel rail pressure. During normal operation, the PCM will output a FP duty cycle from 5% to 51%. The FPDM will run the fuel pump at twice this duty cycle, e.g. if the PCM outputs a 42% duty cycle, the FPDM will run the fuel pump at 84%. If the PCM outputs a 75% duty cycle, the FPDM will turn off the fuel pump.
If the FPDM does not out any diagnostic signal, (0 or 100% duty cycle), the PCM sets a P1233 DTC. This DTC is set if the FPDM loses power. This can also occur if the Inertia Fuel Switch is tripped.
If the FPDM outputs a 25% duty cycle, it means that the fuel pump control duty cycle is out of range. This may occurs if the FPDM does not receive a valid control duty cycle signal from the PCM. The FPDM will default to 100% duty cycle on the fuel pump control output. The PCM sets a P1235 DTC.
If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC.
Keep us updated.
