  Q: How to service and repair the windshield washer pump on Mercury Mariner?

  A:

  Parking the vehicle in neutral position on a hoist is the first step before removing the RH front fender splash shield. The electrical washer pump connector must be disconnected after reading associated safety warnings on labels and consulting medical professionals for emergency protocols because wrong steps can lead to severe workplace injuries. The connector requires protection from hand tool usage while replacing or removing the washer pump hose. Before removing washer pump hoses the vehicle operator should drain fluid from the windshield reservoir to stop fluid leaks. Begin by twisting the lock ring to rotate 90 degrees before the hose will slide out easily. Installation success depends on seating all hoses completely along with locking them into position but keeping away the lock ring from disassembled states because this disassembly weakens the ring and leads to leaks during reassembly. For new washer pump installations circularly position the lock ring while avoiding damage to the rubber grommet. Operating the washer pump before filling the windshield Washer Reservoir may result in early pump breakdown. The installation process ends by following the opposite steps of removal while adding windshield washer fluid to the reservoir.
