Hi,
Water does nto come out in my wagon's rear wiper washer. I tried to check if the washer spout is clogged by using a needle. next it i pryed open the check valve near the tailgate pillar or i would say rear speakers. How would i know if the check valves are working properly? I can hear the washer motor making a humming sound but no water comes out?
thanks

The check valve keeps the fluid from draining back into the tank. If the tube is empty of fluid, suspect the check valve. Hold the washer button in for at least 10-15 seconds to make sure fluid is being pushed to the back of the car. Look under car for leaks, especially by the right front wheel.
