1993 Aerostar rear wiper motor replacement

First, disconnect the battery. Remove the rear door panel. Remove the wiper arm from the outside of the tail gate. Next, disconnect the wiring to the motor. Chances are the motor is rivited into place unless it was already replaced once. You need to drill out the rivits, remove the old motor, and replace the new one using nuts, bolts and lock washers. Reverse the sequence to replace it.

Let me know if you have other questions.

PS: Are you sure the motor is the problem? Is there power to the motor and it still doesn't work?

It will be either bolted or rivited to the door. Can you tell me which it is?

Okay, I'll do my best. The wiper arm is on a splined shaft from the motor. On the underside of the arm (where it mounts to the shaft) there is a small slide that prevents the arm from coming off. Pull the arm away from the window as far as it goes and then slide the the retainer slide away from the shaft. At that point, you can release the wiper arm and it should hole the retainer slide in place. Next, simply pull on the arm where it attaches to the shaft and it should come off. Take your time because sometimes the aluminum arm gets corroded to the steel shaft.

Let me know if this helps. If I can find pictures, I send them to you.

I'm sorry, but I don't have a picture, only directions. If you run into trouble, let me know and I'll try to help you.

Feel free to ask away.

What do you need? On our home page under the do it yourself section there are directions for how to check them and access them. Let me know if that helps or if you have other questions.

That is strange. The fuses would be in the fuse block. Are you able to remove the switch and check to see if there is power out when you try to lock the doors? If do, do it on the driver's door.

Let me know.

Joe

You can use a test light to see if power is present from the switch when you actuate the switch. If you have a volt meter, that would be better to make sure you are getting 12 volts.

Let me know what you find.

Chances are the switch is bad. Internally, it has to change the polarity to the solenoid for the button to go the opposite way. If you check for power, you will most likely see that power comes out of the switch when the lock works, but no other wire will provide power when you do the opposite. If you do get power in both directions, then you have a break in the wiring to the solenoid.

No, the driver's side supplies the power to the other. If you have power in on the driver's side but not out, that is where the problem most likely lies.

Let me know.
