Why Do My Wipers Work Only Some of the Time?
Kemah · November 2026 · From our shop records
The wiper motor had an internal short to ground, so we replaced the motor and the combination switch. Wipers that worked only some of the time sent a driver to our Kemah shop at 79,000 miles, and the trouble had started that week. The owner had tried the intermittent wiper setting and was not sure whether any sound came from the wipers. Our tech inspected the wiper system and found the motor drawing excessive current, which made the wipers run slow and on and off. That extra current had overheated the wiper switch.
