Checking the electric drive
1. Remove the door panel.
2. Disconnect the A 6P connector block from the windshield wiper drive.
3. Check the operation of the drive in each direction by connecting the battery power and ground according to the table. When the drive stops, disconnect one of the wires immediately.
4. If the electric drive does not work or works with sticking, replace it.
Checking the pulsator
5. Connect the 6P connector block to the window lifter drive.
6. Check the voltage between the terminals.
There should be battery voltage between terminals No.1 [6] (+) and No.2 [5] (-) with the ignition key in the "ON" (II) position.
Connect an analog voltmeter to terminals #4 [3](+) and #2 [5] (-) and turn on the low or high speed of the windshield wiper motor. The voltmeter needle will fluctuate (the digital voltmeter will show an average voltage of 0-5 V).
Connect an analog voltmeter to terminals #5 [2](+) and #2 [5] (-) and turn on the low or high speed of the windshield wiper motor. The voltmeter needle will fluctuate (the digital voltmeter will show an average voltage of 0-5 V).
7. If the voltage is not as specified, perform a test of the input signals (at terminals No.5, 6 and 7) of the main power window switch.
8. If the switch is OK, replace the window lift drive.
9. Setting up the window lift control unit.
