GMC Trunk Release Switch

What does a trunk release switch do?

The trunk release switch, also known simply as the "car trunk release" or "trunk release button," is a component commonly found in vehicles with a sedan, coupe, or other traditional body styles that feature a separate trunk compartment at the rear of the vehicle. The trunk release switch is used to electronically unlock and open the trunk lid.

The trunk release switch is typically located inside the vehicle's cabin, often on the dashboard, center console, or driver's door panel. When pressed or activated, the switch sends a signal to the vehicle's electronic control system to release the trunk's locking mechanism. This allows the trunk lid to be opened without using a physical key. Some vehicles also have a remote trunk release function, where pressing a button on the key fob or using a dedicated button on the remote control can activate the trunk release mechanism.

Trunk release button not working

If the trunk release button in your vehicle isn't working:

• Check remote: Test if the remote trunk release on the key fob works.
• Inspect button: Look for physical damage or sticking on the button.
• Check fuse: Verify the trunk release fuse isn't blown.
• Test other buttons: Check if other door release buttons are also not working.
• Check wiring: Inspect wiring and connections for damage.
• Security override: Check if a security feature is blocking the release.
• Remote programming: Reprogram the button if needed.
• Electrical issue: If unresolved, consult a professional mechanic.
