2005 Buick Rainier Washer Pump

You should lift the Wiper Blade assemblies off of the windshield glass, clean the wiper blade element with a clean cloth saturated with full-strength washer solution, rinse the wiper blade assemblies with water and place the wiper blade assemblies back onto the windshield glass.

You should install a new level sensor switch grommet into the washer solvent container, lubricate the grommet with washer fluid to aid in the installation of the level sensor switch, ensure the square tab is positioned vertically to the washer container, push inward to seat the level sensor into the grommet and install the washer solvent container.

You should disconnect the electrical connector from the rain sensor, carefully pull downward on the sensor to release it from the retaining ring, and remove the sensor from the vehicle.
