Q: What are the two methods used to retain the rubber wiper blade element to the blade assembly on Oldsmobile Cutlass?
A: Two methods retain the wiper blade element. One uses a red press-button; press it to slide the element off and push the new one until it locks. The other has a spring-type clip at the element's end. Pinch the retainer to slide the element out. Use pliers if needed. Ensure the metal insert goes through the blade assembly's tabs when installing a new element.
Q: How do you remove and reinstall the wiper arm/blade assembly for Oldsmobile Cutlass?
A: To remove the Wiper Arm/blade assembly, pull it away from the windshield glass while counteracting the tension of the wiper arm spring. Then, depress the small tab located below the wiper arm at the blade connector socket and detach the blade from the arm. In some cases, a coil spring blade retainer may be present, in which case you should insert a screwdriver on top of the spring and push downwards to remove the blade. To reinstall, simply reverse the removal process, ensuring that the connector is fully pushed onto the arm and that the small locating 'pip' securely fits into the hole in the connector.
