What is a Windshield Wiper Transmission Linkage and where is it Located?
The windshield wiper transmission is an integral component of your vehicle’s windshield wiper system. It is a mechanical device made up of multiple linkages that connect the wiper motor to the two wiper arms, transferring the power generated from the rotational movement of the motor when it is activated by the wiper controls into the sweeping back and forth motion of the windshield wiper arms which the blades that clean the windshield are attached to. The wiper transmission thus allows for the wiper motor and arms to work together without hitting each other. The multiple sections of linkage are joined and held together by rivets, while bushings are mounted to the wiper linkage arms and act similarly to bearings. Together, they make it possible for the different sections of the wiper linkage assembly to be able to rotate and pivot during this process.
On most vehicles, the wiper linkage assembly is located under the cowl at the base of the windshield and hidden out of view. This protects the mechanism from being exposed to outside elements and allows for it to operate quietly when being used.
How Do I Know if my Windshield Wiper Transmission Needs to be Replaced?
Windshield wiper transmissions are the most common failed parts of the wiper system and can require replacement for multiple reasons. The biggest cause of damage to wiper systems is frozen wiper blades stuck to an icy windshield during the cold winter season. Turning on the wipers without properly un-sticking both wipers forces the wiper motor to put excess stress on the wiper linkages and arms. This stress can cause plastic connectors to break, pivot points to elongate, or knurled wiper studs which the wiper arms attach to be rounded off. Heavy snow and ice can also force the wiper motor to put excess stress on the linkages and wiper arms, as can large amounts of dirt, causing similar outcomes. A windshield wiper linkage assembly will also make an annoying clunking or squeaking sound when they wear out from prolonged use over time.
A broken or damaged windshield wiper linkage assembly can cause the wipers to not work or work incompletely, which can be quite hazardous for you and for those drivers around you. Therefore, if your wiper transmission has failed, obtaining a replacement and getting it installed quickly is highly recommended.
Can I Replace a Windshield Wiper Linkage Assembly Myself?
Replacing the wiper transmission is a moderate task that may require a specialty tool (available at most auto part stores) to remove the wiper arms from the transmission shafts. From there, removal of the wiper motor and disconnecting the transmission from the vehicle should be all that’s left to get the old / broken parts out. This of course may vary on some applications.
