Question about 2003 Ford Windstar
After a short trip to the grocery store the van was parked outside for about an hour. On returning to the van there was condensation on the interior of the windshield.
Assuming that your heater was in use, it could very well be the beginningstages of your heater core going bad. There are products you can purchase to add to the radiator to prolong the life of the heater core but it has been my experience that while they do work, they are only a short term solution. Try this soon as the core finally rusts completey through you will be dealing with all the engine coolant all over the floor board

if this van has heat in the rear, Id say you have a coolant leak.check antifreeze, and follow hoses back to the rear. look for wet spots on hoses

Body control module (BCM)
Wiper 1 relay
Wiper 2 relay
Windshield wiper motor
Windshield washer pump
Windshield washer nozzles
Windshield washer solvent container
Windshield wiper arm and blade assemblies
Windshield wiper transmission
WIPER/SW 10A fuse
WIPER 25A fuse
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .
