The windshield wiper blades must be checked in the following order. Check the BMW X5 E53 windshield wiper mechanism, tighten its fastening elements. Check the rubber blades for hardening or cracks.
- Wet the windshield and turn on the windshield wipers. Let them work for a while and turn them off. Check the surface of the glass - uneven marks from the brushes or stripes on clean glass indicate that the brushes need to be replaced.
If it is necessary to replace only the rubber blade of the wiper, then use pliers to remove the end of the blade from the frame and remove the old blade completely. Install the new blade in the frame and clamp it with pliers. After replacing the blade, check its operation on the windshield.
