Steps
- Release the front bumper cover
Remove the lower bumper fasteners and pull the corner splash shields back. Disconnect the fog-light and side-marker connectors, remove the fender and upper retainers, then lift the cover away with help if needed.
- Drain the reservoir and remove the old sensor
Place a drain pan below the reservoir and allow the washer fluid to drain. Pull the sensor straight from its grommet, disconnect the electrical plug, and remove the old seal from the reservoir opening.
- Install the new sensor and seal
Fit a new grommet into the reservoir and press the replacement sensor straight into it with its locating tab oriented correctly. Reconnect the electrical plug and inspect the seal for even seating.
- Reinstall the bumper and test the washer system
Reconnect the side-marker and fog-light wiring, align the bumper cover, and reinstall its upper, fender, and lower fasteners. Refill the reservoir, operate the washers, and check for seepage around the new sensor.
