Take the wiper arms off -- you do this by looking under the wiper arm where it mounts on the linkage post (pivot point). There's a bent over piece of metal that is attached to the backside of the arm (toward the rear of the car). Lever it downward with a flatbladed screwdriver. It may help to squirt a bit of WD-40 in the backside of the wiper arm where it mounts over the pivot hub coming through the cowling. This metal piece will come down about 1/2" and is part of a piece that slides up against the pivot hub and holds it in place. When it's in the downward position it allows the arm to pull off the hub.

Remove the screws holding the cowling to the car. There are 4 along the bottom of the windshield and one in the center of the slotted grill in the cowling. These are all Philips head screws.

Open the hood and pull the rubber strip off the front lip of the cowling and you'll find several more screws holding the cowling to the car. Remove these and close the hood.

Pull the cowling up & off the car. You'll now see the motor and linkage. Remove the electrical harness connector by pushing the small red tab up & out of the connector (in the middle of the connector) and press on the flat tab on the connector closest to the outside of the car.

Remove the 3 bolts (10 mm) holding the linkage & motor mount to the car. There is a bolt on either end of the linkage arms and one directly below the motor.

Remove the motor & the linkage from the car.

Remove the 3 small (8mm) bolts and 1 large (12mm) nut from the motor attaching it to the mount.

That's it. Now just replace everything in reverse order & you're all set.

If it is anything like a 91 Ford Tempo, then the wiper motor is on the passenger side near the vent duct for the air conditioning/heating system under the hood. There should be a plastic cover over the length of the firewall that covers the vent duct, washer fluid and the wiper motor.

It should work just fine, they are the same model.

I don't think they made 1982 Trooper. It probably is 1992. If so, you can use 1992 to 2002 Trooper or 1996 to 1999 Acura SLX wiper motor

Remove wiper arms and bladers. Next remove rubber sealing grommets from the wiper spindles. Reomove screws from scuttle panel, then remove scuttle panel, you will now have access to the wiper motor.

To get the wiper motor out you: 1. Lift the cover from the wiper are nut and take it off. 2. Pull the wiper arm off of the motor. 3. Remove the shaft seal, outer bushing nut and outer bushing. 4. Remove the trim panel from inside the hatchdoor. 5. Disconnect the electrical connector from the motor. 6. Remove the bolts and take the motor off.

The 1992 Jeep Wrangler wiper blade sizes are 11" wiper blades on both sides front and a 16" rear wiper (if applicable). 11" wipers can be difficult to find in stores. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.

Pull the valance off the bottom of the wind shield.

my windshield motor is working great, but the spline that the wiper arm sits on is worn out. do i need to replace the the motor or can i purchase another spline. thank you Ron

I am going with the assumption that question is "how do you change the wiper blade (blade and frame)", not "how do you change the rubber blade (wiper refill)", and not "how do you change the wiper arm". Wiper Blade = The wiper frame that attaches to the wiper arm including the rubber blade. 1. Step 1 is to be sure you get the right replacement wiper blades. The 1992 Ford F-Series Pickup (including the F-350) takes 18" wiper blades on both sides front.

There is a wiper motor that when it goes out must be replaced. It happens on older models.

The 2001 does not have a coolant sensor port in the head like the 1992. All sensors and wiring are different.

The first step on how to change the motor on a 1992 Chrysler LeBaron V6 3.0l is to position the vehicle to where you can get the hoist in and out.

I changed mine (1992) by removing the vented piece that runs between the windshield and the hood. Pop the hood and you will find screws to remove this as well as a a few screws from the top in between the grill type vents near the wiper blades. ( Remove the wiper arms and unscrew th antennae also) Lift this pc. out and you will gain access to the nuts that secure the motor to the firewall. Remove the motor harness, then disconnect the motor from the wiper connector. Try new motor by connecting to the harness and turning it on from the cab BEFORE you take anything apart. This will verify taht the motor is the problem. Good luck!

It's possible that the wiper switch is bad, but most likely it's the wiper motor itself. Wiper motors have an internal switch that only turns off when both the manual switch is turned off AND the wiper blade is in the park position. If the wiper motor cannot sense that it has hit the park position, it will run continuously.
