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.
Rear Window Lock-Out Feature
Rear window lock-out switch is integral to Driver Door Switch Assembly (DDSA). When it is pressed momentarily, LED indicator is illuminated, and DDSA receives switch signal. DDSA sends a message over power door serial data line to Driver Door Module (DDM) indicating switch is active. DDM then sends a message over power door serial data line to both rear door modules, prohibiting rear windows from being operated from rear door window switches. Rear windows can still be operated from DDSA.
