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.

lift the arm away from the windshield. if the tension spring is damaged or broken, the arm will not show

resistance. if it is working properly, then pull the arm back until the hinge locks in a verticle position.

remove the retaining nut at the bottom of the windshield wiper arm and pull the wiper arm off.

slide the new wiper assembly on.

tighten the retaining nut and lower the arm back down to the windshield. you will need a wrench and

socket set. good luck!

Open the cap at the end of the windshield wiper arm at the cowl of the Blazer. This will reveal the bolt that secures the wiper arm to the wiper linkage.
Unbolt the wiper arm using a 3/8-inch ratchet and socket. Place the bolt to the side, as you will reuse it later.
Pull the wiper arm up at the blade so that the blade of the wiper is pointing into the air. Then pull at the base of the arm, wiggling it slightly. It's a keyed gear, so it may take a little bit of work to break it free, but with the right amount of wiggling, it will disengage.

REMOVAL & INSTALLATION
(see Figures 1 and 2)

To remove the arm from the pivot, lift the arm to permit the latch to be pulled out to the holding position and remove the arm from the pivot with a rocking motion.

Fig. 1: Mount the wiper blade/arm as shown-Dakota models

Fig. 2: Mount the wiper blade/arm as shown-1994-96 Pick-ups

When installing the arms, the at-rest position of the blades should be determined before pushing the arm onto the pivot. For Dakota trucks, the tip of the driver's side blade should be 0.51-2.63 in. (13-67mm) above the cowl panel and the passenger's side blade should be 0.94-3.06 in. (24-78mm) above the cowl panel. For 1989-93 Pick-ups and Ramchargers, the driver's side blade should be 1.84 in. (47mm) above the windshield weatherstripping at the heel of the blade; the passenger's side blade should be 2.24 in. (57mm) above the weatherstripping. For 1994-96 Pick-ups, the wiper motor must be in the PARK position and the wiper blade should be about 0.85 in. (22mm) from the upper edge of the black-out areas at the base of the windshield.


Hope this helps to solve it.

try this steps to adjust your wiper.
1. Place the keys in the ignition, turn the keys to accessory mode (key-on/engine off), and make sure the wiper motor switch is in the off position. Turn the ignition switch to the off position and remove the keys. The wiper arms are now in their parked position, although may not be properly aligned.
2. Access the bottom of the compromised wiper blade arm. You may have to open the hood or remove the wiper arm cowling (refer to the owners manual for the removal of the cowling on your specific vehicle if required).
3. Locate the retaining nut at the bottom of the wiper arm assembly. Some models will have a protective plastic cap covering the nut. Other vehicles may have a hinged cover that is part of the wiper arm itself. Pry the cap off with a straight-edge screwdriver or unsnap the hinged cover by prying it up from the bottom of the wiper arm with the screwdriver to reveal the retaining nut.
4. Hold the wiper arm stable with one hand and remove the nut with the ratchet and a socket with the other.
5. wiggle the wiper arm gently with one hand while gently prying the base of the arm off the splinter wiper arm stud. The stud has a small spline that holds the wiper arm in the correct position unless otherwise compromised. The wiper arm will feel secured to the stud, but the combination of wiggling gently and prying with the screwdriver will work to remove the arm.
6. Place the arm back into the splined wiper arm stud by positioning it in the off position. some vehicles may have a wiper arms stop that the arm rests in the off position. If so, make sure that the wiper arm is resting against the wiper arm stop when replacing it on the stud.
7. Replace the retaining nut and tighten with the ratchet socket. repaet this procedure with the other wiper arm if desired.
8. use 2 sets of pliers to bend the wiper arm back into position if the wiper arm has been bent. Hold the wiper arm with one set of pliers to anchor it and use the other set to bend it so the wiper is perpendicular to the windshield. If the arm is bent too badly,replacing the wiper arm maybe a more viable option.
9. Inspect the wiper blades.check them for tears in the rubber blades, dry cracking or flimsiness.Replace the wiper blades if necessary.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.

the Windshield wiper blades have little clips that lock them in place. Most replacements have direction on how to release these, as they are common to all models, and remove and install the new ones. If you are talking about the Windshield wiper motor itself i recommend you get a Haynes repair manual on your vehicle so you have the step by step instruction on how to remove and replace this part.

insert scewdriver between wiper blade and wiper arm and apply a little force to remove wiper blade
