Installation recommendations

Generally/typically for this type of part, the exact procedure for replacing the electric sunroof motor may vary depending on the specific design of the car and sunroof mechanism. Below is a safe and practical general procedure for replacing an electrical part of this type.

1) Before assembly

• Check that all markings on the original and new part match, especially 0390200072, 8401NC and 1607362980 if applicable.
• Compare the connector, mounting, motor body shape and location of mounting points.
• Inspect the condition of the transmission part and the surrounding mechanical elements, whether they are visibly damaged, dirty or blocked.
• Disconnect the battery before starting work, especially if you will be handling the wiring.

2) Necessary tools and materials

• set of common hand tools
• screwdrivers and bits of corresponding types
• ratchet and suitable attachments
• plastic pry bar for panel removal
• cleaning agent for electrical contacts
• clean cloth or towels
• work lighting

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and turn off the ignition.
2. Disconnect the battery and wait until the electrical system is de-energized.
3. Remove any necessary covers or trim to gain safe access to the electric sunroof motor.
4. Document the original storage of the part and the wiring, for example with a photo before disassembly.
5. Disconnect the electrical connector and check its condition, cleanliness and any signs of oxidation or overheating.
6. Unfasten the original electric motor and carefully remove it to avoid damaging the surrounding mechanism.
7. Compare the old and new part side by side, especially the mount, connector and serial numbers.
8. Clean the contact surfaces and the surrounding area of the assembly from dust, grease and dirt.
9. Place the used electric motor in place without force and check that it fits correctly into the mounting position.
10. Attach the part back in the original way and then connect the electrical connector.
11. Check that the wiring is not pinched, twisted or in contact with moving parts of the mechanism.
12. Reinstall the removed covers and trim.
13. Connect the battery and perform a basic functional test.
• 4) Post-assembly checks and test drive/function verification
  • Verify that the sunroof opens and closes smoothly, without unusual noises or stuttering.
  • Check the control response in both directions of movement.
  • Watch the mechanism for overloading or stopping in non-standard positions.
  • After the first test, visually check the fastening of the part and the connector again.

  5) The most common assembly mistakes + how to avoid them

  • Part exchange based on similar appearance – always compare serial numbers and connectors.
  • Installation without checking the mechanism – if the guide or mechanism of the sunroof is seized, the engine may be overloaded.
  • Damage to the connector or wiring – disconnect and connect the connector carefully, without prying the wires.
  • Insufficient seating of the electric motor – before tightening, check the correct position and seating of the part.

  Reasons why the part is damaged

  • long-term mechanical overloading of the skylight
  • stuttering or increased resistance of the sunroof mechanism
  • intrusion of moisture into the electrical part or connector
  • oxidation of contacts and deteriorated electrical connection
  • wear of the internal parts of the engine during long-term operation
  • careless handling during previous repair or disassembly
