The condenser is too dirty. Lincoln Navigator, a luxury full-size SUV produced by Ford Motor Company, pioneered a new concept of luxury sport utility vehicle. According to relevant information, the fan of the water tank of 20 17 Lincoln Navigator kept turning because the condenser was too dirty. In this case, you can go to the car wash shop and let the car washer wash it with a high-pressure water gun at a proper distance through the protective cover of the front face, which will improve. If the cleaning is not in place, or some places are not cleaned, the fan will still work. If you keep turning, remove the front and clean the condenser, water tank and cover, and the problem will be solved.
