Mazda CX-9 intermittent front windshield wiper failure requiring repeated activation to function on Mazda CX-9

Some Mazda CX-9 owners report experiencing intermittent front windshield wiper failure, requiring repeated activation for proper functionality. This issue may stem from loose or corroded electrical connections at the wiper motor, which can lead to inconsistent performance. Owners have noted that cleaning corroded connections with a contact cleaner can help restore proper electrical contact. Additionally, problems with the intermittent setting may be linked to a faulty wiper relay, which is crucial for controlling the wiper intervals. In some instances, applying electrical contact cleaner to the wiper stalk and cycling through its functions has improved performance, but if these measures fail, replacing the wiper stalk may be necessary. Addressing these concerns promptly can help ensure the wipers operate effectively.
