If you found this page it might have also happened to you: you drive a Ford and your rear wiper suddenly stopped working. After browsing the internet a bit one comes to the conclusion, that there are only a few major reasons that could have caused this:
Most often reason: The wiper motor is blocked by dirt that entered it over the years through corroded isolation
Rare: A cable on the end of the hatch broke because of the bending when opening and closing the trunk
Almost never: some other problem with the electric like a faulty relais.
In this case it was actually the blocked motor. On the first picture underneath you can already see the residue of salt and sand outside the engine. Open it up (2nd picture), and you come across a gooey mass of dirt, which supports the idea that contamination caused the motor to fail. From here you can do two things: Open it up even more, try to clean it the best way possible, build it in again and hope it works or get a new or used replacement.
The repair descriped here is was done on a Ford Focus (2nd generation) and can be performed by anyone with a little manual dexterity. This guide should be applicable to nearly all Fords.
1st Remove wiper arm
- Flip up the screw's cover as shown on the figure.
- Unscrew the screw with a 13 key
- Most wiper arms sit very firmly. With the help of pliers you can pull it by wiggling it a bit. If you want to avoid damage, protect the area where you apply the with a cloth (as it was not done here ;))
2nd Remove the plastic cover from the trunk lid
- Open the trunk and remove the 4 screws
- After this you can simply remove the cover by pulling it. A little force is necessary though, because it is attached to the bodywork by strong steal clips (first picture)
- Caution: When you pull the cover watch out for the little plastic parts the the screws sat in. Since these are both pinned to the body and to the cover they usually fall on the floor (2nd and 3rd picture)
3rd Remove the wiper engine
- First pull the power plug
- Unscrew the screw to which a cable from the wiper motoris is attached.
- Now remove the three screws, that hold the engine itself
- Pull the engine gently, the only resistance comes from the piece that goes through the whole in the window.
4th Get a replacement
- Write down the model number of your windshield wiper motor, this is usually stamped on the back and starts with e.g. XS
- If you want a new engine, just drive to your neared Ford dealer or to a distributor for spare parts.
- In case you are also ok with a used model, you often find a replacement on ebay or similar websites. Search tip: don't try to find your exact model number, as most sellers name the offer more general and ask the seller for the exact model number or whether it's compatible with yours.
- One site I found In the Netherlands actually offers a broad range of spare parts, that come from a group of auto recyclers here www.getparts.nl. Maybe there are similar sites in your country. For the wiper motor depicted underneath it took 2 days between order and delivery and cost € 45 incl p&p.
