Cascada Passenger Seat Motor Failure & Repair Solutions

As someone with moderate experience working on cars, I had a very similar issue with my 2016 Insignia diesel. The electric seat adjustment completely failed on the driver side and displayed error codes. The root cause turned out to be a heavily discharged battery that wasnt providing enough power to the seat motors. This affected the seat harness and electrical components. After diagnosis, the workshop found the battery voltage was too low to properly operate the seat adjustment system. The fix involved: Testing the seat wiring connections, Checking the seat switch functionality, Replacing the depleted battery, Resetting the seat control module Total repair cost was 290 for parts and labor. The seat adjustment system worked perfectly after the battery replacement and reset. To better assist with your specific case, could you share: Has the battery been replaced recently? Do other electrical features work normally? Are there any other error codes showing? Does the seat make any noise when trying to adjust it? This could help determine if youre facing a similar battery-related issue or if its something else in the seat wiring system.

Thanks for the helpful details. Just had my 103252 KM service done last month, so the battery is fairly new and showing good voltage. The power seats on the driver side work fine, and all other electrical systems are normal. When trying to adjust the passenger seat, there is a faint clicking sound but no movement. Had my mechanic check the seat wiring harness connections and they appear intact. Thinking it might be the seat motor itself based on the symptoms, but hoping to avoid replacing the entire power seat assembly if possible. Has anyone successfully repaired just the motor component rather than doing a complete automotive seat replacement? Looking for specific repair tips before taking it back to the shop.

Based on your description, this sounds like a different issue than my earlier battery-related problem. The clicking noise with no movement in your power seats typically indicates a failed motor or stripped gears in the seat adjustment mechanism. On my car, I initially thought the same, that I needed a complete seat assembly replacement. However, after further diagnosis, just the motor unit needed replacement. The clicking sound you describe is very similar to what I experienced. The repair involved: Removing the seat covers and padding, Accessing the motor assembly under the seat, Replacing just the faulty motor unit, Testing all adjustment directions Total cost was around 180 for the motor unit plus labor. Much cheaper than a full automotive seat replacement. Key diagnostic points that helped identify the motor issue: Good voltage to the seat harness, Clear clicking sound, No movement in any direction, Other seat functions working normally Before proceeding with repairs, ensure your mechanic tests the power seat switch and wiring connections again, as these are much simpler fixes. But if those check out, the motor unit is likely the culprit based on the symptoms youre describing. The electric seat repair was straightforward once the correct part was identified, and the seat has worked perfectly since the motor replacement.

Thanks everyone for the suggestions. After looking into the symptoms more carefully and getting a second opinion from another mechanic, I can confirm it is indeed the seat motor that failed. The clicking sound matches exactly what others described with their power seat issues. Getting the part ordered now, went with an OEM electric seat motor unit for 165 plus estimated 2 hours labor. Much better than replacing the entire passenger seat assembly which would have cost over 800. Really glad I asked here first and learned that just the motor could be replaced. Will share an update once the repair is done, but wanted to close the loop on this thread. For anyone searching later with similar power seat problems, definitely have your mechanic check if just the motor can be replaced before considering a complete automotive seat replacement. The symptoms that pointed to the motor being the issue were: Clicking sound when attempting adjustment, No movement in any direction, Good power supply and connections, All other electrical features working normally Hoping this helps others troubleshoot their electric seat problems in the future.
