Checking and replacing the rear wiper motor

Turn off the ignition

Stand behind the vehicle and pivot the rear wiper nozzle cover

Remove the nozzle by pinching it with your fingers and pulling it upwards.

Remove the nut using a pair of pliers

Open the trunk

Remove the two plastic screws using the Phillips screwdriver on either side of the trunk lock.

Remove the two screws located in the middle of the trunk panel using the T25 torx key

Firmly grasp the trunk panel and pull it down to unclip it.

Access to the engine is now free

Disconnect the electrical connector from the motor by pulling on it

Turn on the ignition

Using a multimeter, measure the voltage at the connector terminal (middle terminal (+) and one of the outer terminals (-)

Here the voltage is correct (around 12V), the motor is therefore correctly supplied but does not work, so it must be replaced

In step 4, if no voltage is detected at the wiper connector terminal, the problem is upstream of the motor. Relays and fuses should be checked.

With the ignition off, sit in the passenger seat, open the glove box and empty it. Unhook the jack holding the glove box. Press simultaneously on the two plastic tabs. The glove box opens.

The fuse box is located at the back on the right.

Using a flashlight and fuse pliers (present by default in the fuse box), remove and check (visually, or using a multimeter) the fuses and relays circled in red

Replace faulty relays/fuses. Return to step 4 and test for voltage at the wiper motor connector terminals.

Unscrew the three screws holding the engine to the body using a ratchet and a 10 mm socket.

Disconnect the windshield washer hose (black rubber tube)

Remove the motor and replace it with a new one

Repeat the steps in reverse order for reassembly.
