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.

remove the wiper arms from the pivots
cycle the wipers through their travel to a park
install wiper arms back on in the parked position

This is a very simple procedure and will save you lots of money by replacing it yourself! A common replacement item on GM vehicles, it should be readily available at your local auto parts retailer and should take no more than a half-hour with just a couple of tools.


• Turn the ignition key to the OFF position.
• Remove the Connector Position Assurance (CPA) and disconnect the wiper motor electrical connector.

• Remove the three screws that secure the cover to the wiper motor and remove the cover.
• Inspect for sealant on the inside of the cover and then discard the cover and screws. Important: If sealant was found on the old cover, it will be necessary to remove any old sealant from the motor housing in Step 6.
• Carefully remove the module (circuit board) from the wiper motor by lifting up on the end of the module electrical connector.
• If necessary, remove any old sealant from the wiper motor housing (refer to Step 4). Notice: When handling the new module in the next step, be careful not to damage or band the electrical contacts on the bottom side of the module.
• Install the module into the wiper motor housing, making sure that the module is fully seated. When fully seated, the edges of the module circuit board will be flush (even) with the motor housing along all sides.

• Carefully apply a bead of silicone sealant, P/N 12345739 (or GE-162 sealant or equivalent) in the groove of the NEW cover (Figure 2). Remove any excess sealant that is outside of the groove. Important: Only apply enough sealant to fill the groove in the cover.
Install the new cover on the wiper motor housing and install the three new screws.
• Tighten the screws to 2.6 N·m (23 lb in).
• Reconnect the wiper motor electrical connector to the wiper motor assembly and install the CPA.
• Turn the ignition key to the ON position and check the wiper system for proper operation (delay/low/high/etc.).

One can get a repair kit that includes a new motor pump and wiring clips, or

one can get the original motor that plugs into the windshield wiper fluid reservoir.

Windshield wiper reservoir (gives idea of how to change the windshield wiper fluid pump motor) Removal & Installation To Remove:

1. Disconnect and isolate the negative battery cable.
2. Raise and safely support the vehicle.
3. Remove the right front wheel and splash shield.
4. Disconnect the electrical connectors from the pumps and detach the rear washer hose.
5. Place a drain pan under the reservoir if it contains fluid.
6. Disconnect the front washer hose at the wiper unit in the engine compartment. NOTE: The front hose will be removed with the reservoir.
   
7. Let the fluid drain from the reservoir.
8. Remove the mounting screws and the reservoir.

To Install:

1. Install the fluid reservoir with the mounting screws.
2. Connect the front washer hose in the engine compartment.
3. Connect the electrical connectors and rear washer hose.
4. Install the splash shield.
5. Install the right front wheel.
6. Lower the vehicle.

You should be able to replace rear wiper easily with rain x or other brand wiper instructions in the container

Remove the outer wiper arm. Remove inner tailgate coverings. Disconnect wiper electrical connector and retaining bolts to remove. Installation is reverse of removal

According to the Haynes repair manual Chapter 12:

1. Disconnect the negative battery cable
2. Detach washer hoses, lift the wiper arm covers and mark the wiper arm locations on the pivot shaft for later re-installation. Remove the wiper pivot nut and remove the wiper arms.
3. Remove the cowl cover (from chapter 11)
3a. Remove the wiper arms then remove the screws that hold the lower area of the cowl cover to the wiper module.
3b. Disengage the quarter turn fasteners that hold the outer ends of the cowl cover to the wiper module.
3c. Open the hood and release the wing nuts that hold the front of the cowl cover to the wiper module.
3d. Close the hood but do not latch it. Now remove the outboard screws and lift the cover up enough to get to the washer hose.
3e. Disconnect the washer hose from the right washer nozzle. Close the hood but do not latch it. Lift the cowl cover toward the windshield and off the vehicle.
3f. Installation is the reverse of removal
4.Open the hood. Disconnect the wiper motor electrical connector.
5. Disconnect the windshield washer hose from the coupling inside the unit. Disconnect the drain tubes from the bottom of the wiper unit.
6. Remove the wiper unit mounting bolts. (Picture appears to be three (possibly allen head) bolts)
7. Remove wiper unit.
8. Installation is the reverse of removal. Wiper blade and wiper arm adjustment is measured with the wipers parked; correct adjustment is the lower wiper arm approximately 1.5 inches distance from the cowl cover and the upper arm approximately 2.5 inches from the lower arm. Operate the wiper motor and check that the wiper motor parks when the wiper switch is OFF.

REMOVAL & INSTALLATION
(I made images larger at the end of instructions)
See Figures 1, 2 and 3
