Default Low washer fluid warning

Still on after filling fluid. It came on during a rain storm.
Any one know if its a sensor in the washer fluid tank?

I let the washer fluid go dry on my 2000 LS.
When I refilled, the warning stayed on.

I took the easy route .... poked at the stuck float with a coat hanger.
Magically, it free'd up and the warning turned off.

Easy fix, took a minute or two.

Tried the hanger trick with no luck.
Is there a float in there? I must have missed it.
I thought it might be some kind of sensor.

you can just unplug the sensor. its a plug at the bottom front of the washer bottle.

Thanks, I saw the plug & will unplug it. I thought if you unplugged, it would stay on all the time so thanks for the advice.

HEY MARK.


was your problem solved by just unplugging the sensor? I have the same with my 98 ls 400 and it's driving me nuts.

Hi

The above will switch the light off but it will also disable a useful feature of the car.

The actual fix is not hard at all - To fix you need to remove the float switch which is accessible from under the washer bottle - it is held in place by a rubber gromet - to remove just wriggle it out and it will come out - you then need to dry it out on a heater ( i left mine on the heater for a week and afterwards gave it a coat of varnish to make it water proof before putting it back in)and then pop it back in again - thats it

The reason why the light come on is becuase the polystyrene float absorbs water over time and gets heavy and sinks tripping the switch and causing the washer fluid light to stay lit

hope this helps
