About this part
The window regulator on your #3 HX21 moves the glass up and down. A broken cable, worn motor or failed mechanism leaves the window stuck or dropping – replacement is needed to use the window safely.
Frequently asked questions
What should I check when buying a window regulator for the Smart #3?
Match the exact door position (front/rear, left/right) and the model year of your #3 HX21. Check whether the motor is included or sold separately, as this varies by supplier.
Should I replace the regulator and motor together?
If the motor still works, replacing just the regulator mechanism is fine. If both are old, replacing the complete unit saves time and avoids a repeat failure.
