Typically, the 2006 HUMMER H3 uses a 22-inch driver-side and a 21-inch passenger-side front wiper blade, with an 11-inch rear blade.
For the 2006 HUMMER H3, replacing the wiper blades follows a common SUV pattern: a two-front-blade setup and a smaller rear blade. Sizes can vary by aftermarket brands and production tolerances, so it’s wise to verify before purchasing. This guide provides the standard measurements and how to confirm them on your specific vehicle.
Front wiper blades: driver and passenger sides
The two front blades on the 2006 H3 are typically mounted as a driver-side blade and a passenger-side blade. Use the following sizes when shopping for replacements:
- Driver-side: 22 inches
- Passenger-side: 21 inches
These sizes are compatible with most OEM configurations and aftermarket replacements for the H3. If your windshield frame or mounting arms have nonstandard adapters, you may need to adjust or use adapters provided by the blade manufacturer.
Rear wiper blade
The H3 also has a dedicated rear window wiper with a smaller blade. The standard size is:
- Rear: 11 inches
Note that some aftermarket blades use 12 inches or have different mount styles, so check the packaging for the correct hook style (most common is a J-hook or universal fit). If your rear arm uses a different adapter, you may need a specific model or adapter kit.
How to confirm blade size for your vehicle
To be certain, measure the existing blades or consult your owner's manual. An easy check is to remove the blade and measure the length from tip to tip, ensuring it covers the windshield effectively without overhang. Retail packaging and fit guides from brands like Bosch, Valeo, or Rain-X list the blade length and adapter type for the H3. When in doubt, bring the old blade to the store for a direct comparison.
Tips for installation and buying
When shopping, look for multi-fit or dealer-fitted blades. If your H3 is equipped with the original equipment blades, you may need to choose a 22" and 21" pair for front, and 11" for rear. Some suggestions: Bosch ICON, Valeo 900 series, or Rain-X Latitude with appropriate adapters. Most retailers offer both OEM-style and universal adapters. Always ensure the product includes the correct attachment system for your wiper arms.
Summary
The 2006 HUMMER H3 uses a 22-inch driver-side, 21-inch passenger-side front wiper blades and an 11-inch rear blade as standard. Verify with your manual or by measuring your current blades, and choose blades that fit your attachment style. Replacements are readily available from most auto parts retailers, and many brands offer compatible aftermarket options.
