How to Turn On the Rear Wiper of an Older BMW X1?
1 Answers
Turn the rear wiper control switch clockwise to activate the rear wiper and clean the rear windshield. Precautions for using the wiper are as follows: 1. Maintain cleanliness: If streaks appear on the windshield, the wiper blade may be dirty. Use a towel dampened with alcohol to wipe the dirty parts of the wiper blade. Cleaning once a month can improve the wiper's performance. 2. Check the rubber: If there is a harsh noise from the windshield, the rubber of the wiper blade may have hardened, worn out, or cracked. If the wear is not particularly severe, the owner can use sandpaper to smooth out the uneven surfaces.
