the washer fluid switch and listen to see if you can hear the pump
making noise. If you can, the try disconnecting the washer fluid hoses
and blowing through them to see if they are clogged. If they dont here
are some steps to diagnose a faulty pump.
Fist find the washer pump, should be located at the bottom of the fluid bottle. Second disconnect the harness from the pump, and hook a test light to both terminals. Third have someone operate the switch for the pump and look to see if the light comes on. If the light does come on then the pump is most likely burnt out. Replace the pump and you should be good to go. If you don't have power trace the ground wire and make sure it is connected, then check your fuses and make sure none are blown.
try and fill up the washer bottle with water for test and use it. if you hear the pump work keep using it till you see where fluid is leaking out. my guess is a hose is broken and all the fluid is leaking out
Most washer solvent bottles share a common resevoir. The rear washer pump is located above the front pump. Try filling resevoir completely. If this does not solve the problem, listen for pump howling when you engage it. If it engages & howls & still wont work, possibly rear nozzle is plugged. Disconnect hose to it. If you engage it & it squirts, nozzle is plugged. Try blowing through it with air hose or pick it out with a fine pick. If no noise or fluid either way pump will need to be replaced.
