What can fail
A switch in the wiper motor's plastic cover can malfunction and overheat, causing loss of intermittent wipers, wiper park function, complete wiper failure, or ignition of the plastic cover. Problems are most likely when using intermittent settings or when snow or ice blocks the blades.
What the fix does
Dealers will inspect the wiper motor's date code. Motors built during the suspect period will have the plastic gear case cover replaced at no cost.
