For Lexus RX300 - if you try to spray the wate and can't hear the motor/pump working, then most likely the pump is out of order. Need to order another pump.
1. Pull back the fender on the right hand side, right under the container (don't even have to open any nut)
2. You should find the pump attached to the container - just unplug the power source
3. Pull the pump out of the container (make sure to have a bucket to catch all the fluid) and unplug two pipes connected to it.
4. Install the new pump, and plug the power cable back in.
It could be the windscreen washer motor
It could on the bottom if the washer fluid reservoir - look there first.
If you were in a wreck you could have damaged your washer fluid reservoir or hoses leading to the spray nozzles. Slightly fill your reservoir with water and observe for leaks.
A Dodge Dakota does not have a rear washer fluid reservoir. On most newer vehicles the washer fluid for the rear windshield comes from the washer fluid reservoir from under the hood. If you are not getting wahser fluid to the rear windshield it could be that the line is frozen or clogged with dirt or the line could be disconnected somewhere.
If Your Question Is That You Are Not Getting Much Water Onto The Windshield. Look For The Screen To Be Partially Stopped Up In The Washer Fluid Tank Or The Hose. Also You Could Have A Small Hole In The Line Not Allowing The Unit To Pull The Fluid To The Wipers.
Should be the same as the wipers--Check to see if you are getting power to the washer pump - if so could be a bad washer pump
you may have a block in the line behind the pump stopping the fluid
could be blown fuse or short in wiring
It appears to be under the windshield washer fluid tank
You could drive the car to florida or add some salt to the tank, that will melt the ice, then add washer fluid that is temperature rated for your area, so it won't refeeze.
Hyundais have a plastic reservoir that can be cut through by flying debris. OR it could be the pump. OR you could check to see if the hose has become disconnected.
Are you sure it's oil? Most likely is engine coolant from the radiator. Next would be transmission fluid. Or it could be from the reservoir holding the windshield washer fluid. Oil from the front is unlikely.
