Problem overview

Some Ram 1500 owners report experiencing issues with the windshield wiper fluid system, including clogged spray nozzles, leaking hoses, blown fuses, pump failures, and frozen fluid. These problems can hinder the operation of the wiper fluid, especially if the washer pump is not functioning correctly or if unsuitable washer fluid is used in cold temperatures. Additionally, some owners encounter door lock malfunctions, often associated with the trouble code B1300, which may require repairs such as replacing the power door lock actuator. If these issues persist, it is advisable for owners to consult a certified mechanic to properly diagnose and address the windshield wiper fluid and door lock problems.
