I have searched this site for hours about wiper-related issues but I need some advice on how to proceed.
Symptoms: Whenever I turn the wiper stalk to the slow speed nothing happens. Whenever I turn it to the fast speed they run at normal speed (not fast). The intermittants do not work at all. Wipers do not park correctly either. Turn signal, high-low, and window washer works great.
Questions: Is it the stalk, motor, module or a combination of these? How can I test these without having to throw parts at it?
