Today I changed my rear wiper motor as it had stopped working (I'd noticed it was slowing down over a few weeks then it stopped entirely). I took a few pics and thought I'd describe it here.

First the trim around the base of the rear wiper arm pulls off. No particular trick to this, just pry it off with finger pressure.

Then there is a small plastic part with the washer nozzles to take off, again, easily done with light finger pressure.

Now remove the 13mm nut with a socket

now use a wiper puller to remove the wiper arm. And open tailgate then in the hazard triangle compartment there are 6 torx T25 screws to be removed.

4 in a line along the lower edge of the tailgate and 2 just above the emergency triangle itself.




Now get brave and grab the plastic trim and pull it off. Best prepare some means of support and be prepared to take the weight of the trim panel as it comes loose. The reason is the electrical connections to the two interior lights and (if the car has it) the button for electric tailgate close. I used some large boxes which allowed me to rest the trim without the weight being on the cables, long enough to disconnect the connectors and remove the whole trim.

Now disconnect the connector and washer fluid pipe from the motor. They come off easily (just slide the black clip aside to release the washer pipe).


And the motor can can be removed with 3 x 10mm nuts. Here's the old failed motor next to the new one. I guess when I take the motor apart I'll find corrosion inside from the washer fluid.

Reassembly wasnt so bad, again using a means of support so the electrical connectors can be plugged in without straining the cables. When refitting the wiper arm don't tighten the 13mm nut too much until you test the wiper operation as chances are you'll need to slacken off the nut again and reposition the wiper arm to get it to park in the right spot.
