Why can't the wiper blade clean properly when it's frozen?

[LeBrantley]

First, check if the rubber strip of the wiper blade has aged and hardened, which can cause the wiper to not clean properly and produce abnormal noises. When the rubber strip of the wiper blade ages and hardens, it doesn't fit well against the windshield, leaving gaps that result in poor cleaning performance. It is recommended to replace the wiper blade. Identifying damage by sound: If the rubber strip has detached from the frame, it will slap against the windshield with each wipe, producing jumping, shaking, or other abnormal sounds. It is advised to replace the wiper blade promptly. Identifying by cleaning performance: If after each wipe, streaks or marks are left on either side or the middle of the windshield, it is recommended to replace the wiper blade.
