Washer Fluid Level Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative low washer fluid warning lamp condition. If the problem being diagnosed is related to lamp accuracy,
be certain to confirm that the problem is with the lamp or washer fluid level sensor and not with a damaged or empty washer fluid reservoir. Inspect the
reservoir for proper fluid level and signs of damage or distortion that could affect sensor performance before you proceed with lamp diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
1. Check the fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Turn the ignition switch to the On position. Check for battery voltage at the fuse in the junction block. If OK, go to Step 3. If not OK, repair the
open circuit to the ignition switch as required.
3. Turn the ignition switch to the Off position. Unplug the wire harness connector from the washer fluid level sensor. Install a jumper wire between
the two cavities of the sensor wire harness connector. Turn the ignition switch to the On position. The low washer fluid warning lamp should light.
Remove the jumper wire and the lamp should go off. If OK, replace the faulty washer fluid level sensor. If not OK, go to Step 4.
4. Turn the ignition switch to the Off position. Check for continuity between the ground circuit cavity of the washer fluid level sensor wire harness
connector and a good ground. There should be continuity If OK, go to Step 5. If not OK, repair the open circuit as required.
5. Disconnect and isolate the battery negative cable. Remove the instrument cluster bezel and the cluster as described. The washer fluid level sensor
wire harness connector is still unplugged. Check for continuity between the washer fluid level sense circuit cavity of the cluster wire harness
connector and a good ground. There should be no continuity. If OK, go to Step 6. If not OK, repair the short circuit as required.
6. Check for continuity between the washer fluid level sense circuit cavities of the cluster wire harness connector and the washer fluid level sensor
wire harness connector. There should be continuity. If OK, replace the faulty bulb. If not OK, repair the open circuit as required.
