Tips for Poor Wiper Performance in the Middle of Frameless Wipers?
2 Answers
There are no special tricks for poor wiper performance with frameless wipers. You should inspect them as follows: 1. First, check if the wiper blades are worn out. Wiper blades are consumable items and can easily get damaged, especially under harsh environmental conditions. Worn-out blades naturally won't wipe clean. 2. Also, check if the car's windshield surface has dirt buildup. If the windshield hasn't been cleaned for a long time, a layer of grime can form on the surface, causing increased friction during wiper operation, which can lead to noise due to excessive resistance. 3. If the wipers operate under high resistance for an extended period, it may burn out the wiper motor.
I've seen this issue of the middle part of frameless wipers not cleaning properly many times. After decades of driving, I encounter it frequently. It's mainly caused by oil film on the glass surface or aging of wiper rubber. I would first use a wet cloth with some glass cleaner to thoroughly clean the windshield, especially the area covered by the wipers. If the glass looks clean but the problem persists, check the wipers themselves: wipe off dust and residue from the wiper blades with a clean cloth, and use alcohol for heavy grease. If the wiper isn't installed properly, insufficient pressure in the middle area causes poor cleaning - I'd try loosening the wiper arm screw to readjust the position. If all else fails, replace the wipers immediately - don't delay. Regular maintenance is crucial: clean both glass and wipers monthly to prevent dry wiping from damaging the rubber. Though simple, this prevents blurred vision during rain - driving safety comes first.
