Windshield Wipers

Print

See Figure 1

For maximum effectiveness and longest life, the windshield and wiper elements should be kept clean. Dirt, tree sap, road tar, etc., will cause streaking, smearing, and wiper element deterioration. Hardening of the elements will cause the wipers to chatter as they wipe the windshield. Wash the windshield thoroughly with a glass cleaner at least once a month. Wipe off the rubber element with a wet rag afterwards.

Obviously, the item most frequently requiring replacement is the element. It is very rarely necessary to replace the blade or arm unless they become accidentally bent or damaged in some other manner.

Your car is equipped from the manufacture with one of three types of elements: the first type is commonly referred to as the Anco® style; the second type is the Trico® style; and the third is the plastic style which uses a plastic blade assembly. Replacement of any element type is very simple and requires only a few minutes to do.
