How do we determine whether we need to replace the 72250-TEA-T01 right window regulator? Next you can pay attention to the following key signs.
1. Check basic functions
Non-response test: Operate the right window lift switch. If the window is completely unresponsive, it may be a malfunction of the regulator motor, switch or circuit. Use a multimeter to check whether the power supply of the regulator is normal. If there is no power supply, you need to check the fuse, control unit or line; if there is power supply but the motor does not respond, it may be that the regulator motor is damaged.
Partial reaction test: If there is a "click" sound during the switch operation but the glass does not move, it may be that the mechanical parts of the regulator are stuck or broken, and you need to remove the door trim to check the regulator assembly.
2. Observe abnormal phenomena
Abnormal lifting sound: "squeaking" and "clicking" sounds appear during the lifting process, which may be deformed by the regulator guide rail, wear of the steel cable or damage to the motor bearing. You can clean the rails first and apply grease. If the abnormal noise still exists, the regulator needs to be replaced.
Glass incline: One side of the glass is lagging or tilting when lifting, which may be caused by deformation of the regulator bracket or loose fixing screws. Check whether the bracket is deformed. If it is deformed, replace the regulator; if the screw is loose, observe whether it returns to normal after tightening.
Automatic drop: The window with anti-clip function automatically drops when it rises to the top, which may be triggered by the regulator motor overload protection or the anti-clip sensor failure. Check whether the glass and sealing strip are stuck. If the sealing strip problem still falls automatically after it is eliminated, the adjuster needs to be replaced.
3. Test the motor performance
Resistance detection: Disconnect the regulator power supply and measure the motor resistance with a multimeter. If the resistance is infinity or close to 0Ω, the motor will be damaged and the regulator needs to be replaced.
Manual test: After removing the regulator, manually rotate the motor shaft. If the resistance is abnormal, it may be that the internal gears of the motor are worn and need to be replaced.
4. Check the associated components
Sealing strip status: The difficulty in lifting and lowering of glass may be caused by aging and deformation of the seal strip. First clean the seal strip and apply talc or silicon lubricant. If it is still stuck, replace the seal strip.
Circuit Check: If you smell burnt smell or the fuse is blown when operating the switch, it may be that the regulator motor is short-circuited, causing the circuit to be overloaded. The motor circuit needs to be checked. If the motor is confirmed to be short-circuited, the regulator needs to be replaced.
