Hybryd aero wiper blade, 70cm

Cold weather can affect blade life, too. Freezing temperatures makes rubber hard and brittle, which increases the tendency to crack and split. The holders can also become clogged with ice and snow, preventing the holder from distributing spring tension evenly over the blade. The blade "freezes up" and leaves streaks as it skips across the glass.

You can usually replace wiper blades yourself, and can replace just the blade with a refill or the entire blade assembly. Refills will save you money. If you're installing a blade assembly, most come with some type of adapter to fit the arms on your vehicle. The old blades pull or push off the arm by pressing a release button or pin on the wiper holder.

For cold weather driving, you might consider installing a set of "winter blades" on your vehicle. These have an enclosed holder that prevents ice and snow from building up and interfering with the wiper's ability to do its job.

If the blades can be pulled away from the glass with little resistance, it's time for new arms. Most vehicle manufacturers publish tension specs for their arms. If the arm doesn't meet the spec, it needs to be replaced.
