Washer Fluid Sensor

Has anyone experienced an issue with the washer fluid sensor? Mine keeps coming up that it's running low, when it's not. I topped it off, and it came right back on, and comes on every time you start up the Jeep, after a few seconds. Seeing as my B2B warranty just ran out, I'm not about to take it t the dealer.
My guess is the sensor either died or has a loose connection. Seeing as it looks like a pain to get to, I just wanted to see if anyone else has run into this issue and what the problem was.

Google: Windshield Washer Fluid fluid light won't go out. Go to the jeep garage link.

I have the same issue. Looked up as directed seems rain-x causes a lot of the problems. planning to run mine low soon and fill with something other than rain-x to see if that causes it to go away.

"SUBJECT: TECH-TIPS # 14-012 – WINDSHIELD WASHER LIGHT ON AND/OR WASHER LIGHT
WILL NOT GO OUT AFTER ADDING WASHER SOLVENT
Vehicles that use a continuity “electrode” style washer level sensor designed to work with most alcohol
based washer solvents. We have received information that some rain repellant solvents may not register
properly. The rain repellant washer solvents have been found to coat the sensor electrodes with a
residue that will not allow fluid conductivity between the two switch electrodes when they are immersed in
the washer fluid. Some of the rain repellant washer solvents can be any colour, not just orange.
If the customer’s complaint matches the above subject, verify the washer solvent condition and colour. If
the solvent appears contaminated or its condition is unknown, it may be necessary to drain the reservoir,
remove and clean the washer level sensor electrodes with an alcohol based solvent."

Probably won't go away until you disassemble and clean the electrodes. I don't think the residue will simply rinse off, but I hope I'm wrong. Good luck, and let us know how you make out.

It will probably be a few weeks until I get to take things apart to clean it if needed so figure I can use the other fluid I have at home and see how it goes. I'll check back when I get the new stuff in. Also mine is basically on half the time off half the time so I am hoping that it isn't completed coated and there is enough that it can work again and slowly clean off the contacts.

I do run the Rain-X stuff, so that may be my issue. Seems pretty crappy though, as I have ran this fluid in all of my vehicles for over a decade, and not had a problem until now. I've had my Grand Prix for 8 years now, and have run the Rain-X in it since the first time I filled the bottle. Not one issue. I will probably just clean the sensor and go from there.

I am going to see if I can find an easy way to access the sensor, then I'll probably just regularly clean it as I do like the rain-x stuff compared to regular.

Once it truly hits the low level sensor (back when mine worked!), it takes about a gallon to top it off.

I had the same problem...a new sensor is $5 T the dealer and takes 5 min to install. My old one indeed failed because of Rain-x washer fluid (the orange stuff). It formed a film on the electrodes that prevented the sensor from reading the correct level of fluid.

^^^ - Anyone know a good aftermarket fluid to use, or do we have to use Mopar only?

I use the Meijer purple stuff in a Saturn sky, 2010 grand Cherokee, Audi q5, and 2014 summit and have had no problems.
