First thing to look out for before handling, have you filled your cleaning fluid? If so, let’s see what causes prevent your equipment from operating properly.


Causes for wipers that no longer work on your Lexus RX

Very often, your equipment is blocked by accumulated dirt or limescale. This is the main reason that may stop your equipment from working. To remedy this, try to unclog your sprinklers. These holes allow the product to be propelled onto your Lexus RX’s windshield. It is very likely that they are blocked, by accumulation of limestone, or various types of dirt. To do this, you can get started with by trying to blow, yourself or with some powerful equipment, such as a bicycle pump or ideally the tire inflator at your gas station.

How to fix wipers that no longer work

If nothing can be done, try to get yourself a thin, durable object, such as a paper clip, that will allow you to access the interior without losing a piece. We advise that you also use a mixture of vinegar and hot water to optimize your results.
Repeat the test, if it still doesn’t work, maybe it’s blocked at a deeper place, at the connection pipe. This is the link between the pump and the nozzle in your Lexus RX.
To reach it, you will have to open your cover:
You should identify the two hoses specific to each nozzle. Try to tidy them and obviously make sure they are properly connected. Use the same cleaning procedures described above. When they are cleaned, you should be capable to circulate water through them without any problems. Then plug them back in properly, and repeat the test on your Lexus RX. If it still doesn’t work, you now understand that it doesn’t come from the sprinklers or the pipes.
After that, you should consequently check the pump. It is the one who starts the product launch.
You will find it near the cleaning fluid reservoir under your Lexus RX’s hood.
First test to see if it works, when you turn on the washer, you are expected to hear a noise when the pump is activated. In the absence of noise, this denotes that it does not work. It will then have to be replaced.
It is a very basic thing to do . First, do away with the two screws that allow it to be fixed on your Lexus RX.
Then, you must identify two power wires. They are mainly black and red. They need to be disconnected, but be aware, they must be reconnected in the right direction afterwards, or you would create a short circuit on your Lexus RX. A little tip to bear in mind: the red wire represents the + terminal. For example, place a piece of red tape on it to make sure you can find it. Do the same with the black tape on the bollard – . Thanks to this, you definately will reconnect the wire of the right color without any problem later on.
Once completed, you can do away with the old pump and insert the new pump on your Lexus RX. Reconnect the cables properly using the tip, then just screw the two retaining screws back on.
Now run a test again.
Everything should be back to normal by now.
