How to Disable Windshield Washer Level Sensor Dash Light/Notification
 

My windshield washer reservoir fluid level dash light/notification has recently started coming on often. The reservoir is not empty.

Can someone tell me the easiest/quickest way to disable the reservoir sensor? I don't need the dash warning notifications.

Seems like disconnecting the sensor wiring connector might be easiest, but access might be a headache.

Thanks in advance!

To disconnect the sensor, you just need to remove the front passenger wheel and fender liner. There is a connector near the top of the reservoir right next to where the filler neck inserts into the main reservoir body. If you disconnect this connector, you disconnect both the washer pump and the washer level switch. The extension harness going to the bottom of the reservoir is for the washer level switch (the other goes to the pump which should be obvious). Not terribly difficult.

However, I'm not sure disconnecting it will disable the warning light.

Thank you for the reply. Is it possible to disconnect the extension harness for the level sensor at a connector up at the top of the reservoir, or would I have to disconnect it at a connector located on the sensor at the bottom of the reservoir?

R&R procedure (should tell you how to disconnect level sensor) will be in the FSM (link in sig) or you may be able to figure it out using the exploded diagrams at CourtesyParts and others (including the aforementioned FSM).

If pulling the connector from the level sensor doesn't shut off the light, you will need to rig up a jumper to short the wires.

Thank you for the input. I will take a closer look at those diagrams. In the meantime, is it possible that the sensor is just dirty inside the reservoir, and can that be cleaned? Also, I am curious how this sensor actually senses that the reservoir is empty?

If you disconnect the connector up top, you will disconnect the washer level switch and also the washer pump, which means you won't be able to use the washer fluid. If you disconnect on the bottom (can probably do this by removing the front bumper instead of the wheel and fender liner), then you leave the washer pump connected allowing you to continue to use washer fluid on your windshield.

Got it. Do you know how these sensors work, and if I can try to simply clean it while it is installed?

The sensor is pretty cheap to just replace. It has a float that closes a circuit when the level gets low.
