2010 Hummer H3 Switches

What sends people here

A window that only works from one door, or a switch that sticks. On a mid-size SUV, second and third row configuration, rear climate and towing content all change part numbers here.

Why buy OEM here

• Real wholesale. The same switches your dealer sells, at a fraction over our cost.
• OEM, not lookalike. With switches the difference shows up on installation day, not in the photo.
• VIN verified fitment. We confirm the switches number against your vehicle before it ships.

Before you order

Buying factory removes the variable. You are installing what the plant installed. We would rather spend two minutes verifying than process a return next week. Orders confirmed before mid-afternoon Central are on a truck that evening.
