3. Disconnect the headlamp and dash wire harness connector for the washer fluid level switch from the switch connector receptacle.

NOTE: The pivoting float of the washer fluid level switch must be in a horizontal position within the reservoir in order to be removed. With the reservoir empty and in an upright position, the pivoting float will orient itself to the horizontal position when the switch connector receptacle is pointed straight downwards.

4. Using a trim stick or another suitable wide flat-bladed tool, gently pry the barbed nipple of the washer fluid level switch out of the rubber grommet seal on the outboard side of the reservoir. Care must be taken not to damage the reservoir.

5. Remove the washer fluid level switch and float from the washer reservoir.
6. Remove the rubber grommet seal from the washer fluid level switch mounting hole in the washer reservoir and discard.

INSTALLATION
1. Install a new rubber grommet seal into the washer fluid level switch mounting hole in the outboard side of the washer reservoir. Always use a new rubber grommet seal on the reservoir.
2. Position the float of the washer fluid level switch through the rubber grommet seal in the washer reservoir. The connector receptacle of the washer fluid level switch should be pointed downward.
3. Press firmly and evenly on the washer fluid level switch using hand pressure until the barbed nipple is fully seated in the rubber grommet seal in the washer reservoir mounting hole.
4. Reconnect the headlamp and dash wire harness connector for the washer fluid level switch to the switch connector receptacle.
