My windshield washer pump in my Toyota Yaris Verso has stopped working. The fuse seems to be fine, so either it's due to a loose connection, or the pump is broken. What is the likely cause, and how can I access the pump?

Did you ever figure out how to get at the pump? I cruised a Yaris forum for a bit and couldn't find anything. –  Mark Johnson Dec 7 '12 at 2:45
    
@MarkJohnson: thanks for getting back to me. Yes - the pump motor had to be replaced, as simple as that. –  Daniel Gehriger Dec 7 '12 at 8:09
    
Yes, but where was it located and how did you get at it? Folks that find this via search engines will want to know. –  Mark Johnson Dec 7 '12 at 17:55

The pump is usually mounted to the bottom of the tank.

Common causes of failure:

  • Disconnected or clogged hose with the engine off can you hear the motor running under the hood? If so could be a clogged or disconnected hose.
  • Wax or other debris in the jets, if the jets are located on the hood they can get clogged with wax or dirt, if you hear the pump motor running and there are no disconnected or clogged hoses this may be your problem.
  • Bad motor, check for voltage at the terminals connected to the motor
  • If no voltage to the motor you may have a bad wiper switch

Thanks! I don't hear the pump so I guess it's either a bad motor or a bad switch. I'll have to access it first, which isn't easy without lifting the car. –  Daniel Gehriger Oct 30 '12 at 7:31

I've had a faulty windshield washer pump motor changed in my Yaris once. This one is not so easy to access. The mechanic replaced it via front right wheel area after removing front guard. He said this way is better other wise he'll have to remove front bumper, headlight then washer water tank to get to motor. Hope this helps

Welcome to the site! Thanks for the info. Out of curiosity, could you tell us what year your Yaris was? –  Mark Johnson Dec 11 '12 at 1:49
