1. 1

   Check the main wiper fuse and the windscreen wiper relay (designated as K009 at connector X093 in 900 Vario models).

2. 2

   Inspect electrical connector X347 at the front wiper motor for moisture, corrosion, or loose pins.

3. 3

   Perform a voltage and ground test at connector X347 using a digital multimeter to ensure the motor receives power and ground when the wiper switch is activated.

4. 4

   Test related functions, such as the front screen washer pump (M003 at connector X301), to verify the steering column switch is sending signals properly.

5. 5

   Check the wiper linkage for mechanical binding or jammed debris that could cause the motor to time out or burn out.

1. 1

   Safety Prep

   Turn the ignition OFF, remove the key, and disconnect the negative battery terminal.

2. 2

   Locate the Motor

   The M002 front wiper motor is located directly in the front windscreen frame.

3. 3

   Remove the Cover

   Unscrew and remove the protective cover over the wiper motor assembly.

4. 4

   Disconnect the Arm and Wiring

   Unbolt the front wiper arm from the motor spindle. Unplug the X347 electrical connector.

5. 5

   Remove the Motor

   Unbolt the motor from its mounting bracket and detach it from the wiper linkage. (Note: The motor and internal parking switch are generally a single sealed unit and are not serviceable; the whole unit must be replaced).

6. 6

   Installation

   Install the new M002 motor, secure the mounting bolts, and reconnect the linkage.

7. 7

   Reassembly

   Plug in the X347 connector, reinstall the protective cover, and reattach the wiper arm in the correct resting (park) position.

8. 8

   Test

   Reconnect the battery, turn on the ignition, and test the wipers. You may need to clear the inactive 0F.1.1D fault code from the tractor's terminal.
