Why Parts Fail Most Often
Common causes of failure include moisture ingress and corrosion, wear or breakage of small plastic gears inside the actuator, seized mechanical latch due to dirt or rust, and electrical faults such as worn motor brushes or damaged wiring/connectors. Frequent door use, exposure to road salt and moisture, and age-related plastic fatigue are typical contributors.
