Hello. The problem is that no water gets on the windshield wiper. No problem with the rear wiper. So the pump is running. The sound of the pump, which gives water to the rear window, which catches my attention, does not come out when it is desired to spray water on the windscreen. So the pump motor does not work. In the first place, I checked the water outlets on the hood, and even detached and blown the hose, there was no obstruction. The problem seems electrical. I would appreciate if those who can help with knowledge help.
By the way, 1-1.5 years ago, I gave the vehicle to the service from the same problem. They replaced the pump. They used to pack the bag in the old bag. I didn't throw it. Today I tried it at home pump running. It has 2 outputs. Guess the back front. One is white and one is black. When I give 12v, it throws water from one of the outlets. When I turn the 12v over, it throws water out of the other outlet. Frankly, I thought the event was electrical after that. Also, what should I say or changed the service pump. Thanks in advance for the answers.
