About 3 months ago the water pump went out on our Explorer. Simple and cheap to swap it for a new one and all was good.

However, now the new one is not working. As far as I can tell there is no fuse, but I have read about there being a relay. Anyone know if that's true and where the relay is located? $16 is not much to spend on a new pump, but I don't really feel like swapping one out constantly.

Thanks.

 

According to the wiring diagram for your 2008, the washer relay is located withing the front wiper motor assembly. The washer relay gets power from the wiper motor power feed, so if your front wipers are working, your washer should too. The wiper motor assembly gets power from 30A fuse F20 in the Battery Junction Box.

Thanks, the front wipers work fine, assuming the switch for the washer pump in the stalk is also fine, since pushing it in triggers the front wipers.

I visually checked the fuse, wanted to pull it and check with a multimeter, but felt like it was going to break and without a spare I did not want to risk it. Going to try testing the connection next, if that's good it must be the pump.

 

I'm not sure how easy it is to reach the electrical connection at the pump. It's is pretty easy to access, you can try testing for voltage right at the pump.
