Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power Window Calibration
If battery is disconnected, power windows will require calibration to establish upper and lower stop points. Immediately after Central Control Unit (CCU) or battery is connected, CCU will energize down contacts on all window switches. To ensure calibration is successful; ensure that alarm is disarmed and vehicle is unlocked, that all doors and tailgate are in closed position, that sunroof is open to full hardback or softback position. DO NOT open any door until calibration procedure is completed. Turn ignition on, using appropriate window switch raise each window until motor stalls and window is fully closed. Turn ignition off. If calibration is not successful CCU will sound a warning for about .8 seconds and windows will fully lower. If calibration fails, repeat procedure.
