Front wipers on the Hummer H3 are typically 24 inches on the driver’s side and 19 inches on the passenger’s side, with a rear wiper blade of about 12 inches if your model has one. This article outlines the standard sizes and how to confirm the right fit for your exact year.
Front windshield wiper sizes
Knowing the correct front blade lengths helps ensure clear visibility and proper contact with the windshield. The H3 uses two different blade lengths, one for the driver side and a slightly shorter one for the passenger side.
- Driver side: 24 inches
- Passenger side: 19 inches
Using the two appropriate sizes maximizes coverage and reduces streaking, especially during heavy rain or snow. If your H3 is a late-year model or has a specific trim, always double-check the exact size in your owner’s manual or on the existing blades.
Rear windshield wiper size
Not all H3 models have a rear wiper, but for those that do, the blade is a shorter size designed for the rear window’s dimensions.
- Rear wiper: 12 inches
Rear blade lengths can vary slightly by year or aftermarket replacements. If your vehicle didn’t come with a rear wiper or you’re unsure whether your model has one, consult the owner's manual or a parts specialist before purchasing.
How to confirm the right size for your H3
To ensure you buy the correct blades, verify by checking multiple sources and measurements. Start with the manual, and then cross-check on the door jamb sticker, the current blade packaging, or by bringing an old blade to a parts retailer.
- Check the owner’s manual for the exact blade lengths for your year and trim
- Measure the current blades if you don’t have the manual
- Ask a parts counter for your specific VIN or year to confirm fit
If in doubt, replace blades in matched pairs (both sides) to maintain uniform pressure and visibility. OEM or reputable aftermarket blades that match the listed sizes are widely available at auto parts stores and online retailers.
Summary
The standard front wiper sizes for most Hummer H3 models are 24 inches on the driver side and 19 inches on the passenger side, with a 12-inch rear blade if your vehicle has one. Always verify against your year, trim, and manual, as there can be slight variations. When in doubt, consult the parts counter with your vehicle identification number (VIN) to ensure a precise fit.
