• could be the wiper relay contacts are stuck closed causing power (battery voltage ) to be supplied all the time ,or a problem with the GEM module .
  
  Windshield Wiper
  
  The windshield wiper system consists of the following parts:
  
  Windshield wiper arms (2)
  Windshield wiper motor on the air cowl trim panel
  Windshield wiper linkage
  Windshield wiper blades (2)
  Wiper relay, in the central junction box (CJB)
  Generic electronic module (GEM)
  Wiper/washer switch (part of the multi-function switch), consisting of:
  wiper switch
  washer switch (pressure switch) and
  delay control switch (rotary switch, depending on model)
  
  Inspection and Verification
  
  Verify the customer concern.
  Visually inspect for obvious signs of mechanical and electrical damage:

  Wiper blades
  Front wiper linkage
  Fluid reservoir - windshield washing system (level)
  Hoses
  Nozzles

  If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle:
  check that the program card is correctly installed.
  check the connections to the vehicle.
  check the ignition switch position.
  If the scan tool still does not communicate with the vehicle, refer to the scan tool operating manual.
  Carry out the scan tool data link test. If the scan tool responds with:
  ISO or CAN circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
  No response/not equipped for GEM, refer to Section 419-10 .
  System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the GEM.
  If the DTCs retrieved are related to the concern, go to the Generic Electronic Module (GEM) Diagnostic Trouble Code (DTC) Index.
  If no DTCs related to the concern are retrieved, GO to Symptom Chart .

  Normal Operation
  When low speed operation is selected, the windshield wiper motor receives voltage through circuit 32-KA10 (WH/GN). When high speed operation is selected, the windshield wiper motor receives voltage through circuit 32-KA11 (WH/BK). When intermittent operation is selected, the generic electronic module (GEM) sends an intermittent ground signal to the windshield wiper relay through circuit 91S-KA12 (BK/WH). The relay energizes and sends voltage to the wiper/washer switch through circuit 32-KA19 (WH/BK). The wiper/washer switch sends voltage to the windshield wiper motor through circuit 32-KA10 (WH/GN). When the wiper/washer switch is turned to the off position, or between intermittent pulses, the internal run/park switch in the windshield wiper motor provides voltage to the windshield wiper relay through circuit 32-KA9 (WH/BU) until the wiper motor completes its cycle and opens the circuit
  
  Possible Causes
  Circuit 32-KA10 (WH/GN) short to voltage
  Circuit 32-KA11 (WH/BK) short to voltage
  Circuit 32-KA19 (WH/BK) short to voltage
  Circuit 91S-KA12 (BK/WH) short to ground

This is technically for the V6 4.2L but I'm sure those Ford E250's have the same setup for windshield wiper motor. Let me know how it goes.

First I would look in the fuse box by the driver side and check the fuse,if good then get a meter and see if power is going to wiper motor,if so,then wiper motor is bad,if no power is going to motor,then bad switch,here's a link to see.

Windshield Wiper Switch

Print
REMOVAL & INSTALLATION
The windshield wiper/washer switch is part of the Combination Switch Assembly. Refer to Turn Signal/Combination Switch services procedures.

Sorry , no adjustment .
Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

how much to replace motor for windshield wipers

there is 2 wiper motors . 1 for the drivres side and the other for the passenger. sounds like a bad passenger side motor

Hi,
The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.

GL,
Td

The motor is going bad or the gear is getting wore you can visually check the connection to the wipers from under the hood by applying alil pressure to the wiper blades see if the motor keeps pushing or stops but depends on the year of the car it is typical for the motor and or relay to be bad

Wiper motor rarely goes bad, and a second one going bad as well is extremely rare. What will burn out a motor is very high resistance to movement from the wiper assembly. Do the following: Take out the wiper motor, and move the wipers by hand to see if they are hard to move, or if the arms (rod mechanism) are rubbing against anything. Do this with the blades in normal position, resting against the windshield. Pour water unto windshield while testing it, to avoid scratches. One telltale sign for this condition, is the wipers going too slow before complete stoppage. Either that, or an electrical connection leading to the wiper motor, for that simply check that there is electricity in the wiper motor connector when wipers are activated.
