Fuse diagram washer pump fuse

Unlikely to have a fuse covering it and the diagrams say there isn't one. It has a very low current use.

Check the pump itself for voltage using a test meter. It could also be the switch that is faulty.

Do the wipers work ? If so , it's not a fuse issue ,same fuse powers wipers & washers . More then likely it's the washer pump or switch . Looking at a wiring diagram an using a DVOM - digital volt ohmmeter to test for battery positive voltage to the pump would be the thing to do.

WHAT IS UR PROBLEM EXACTLY?THE WASHER PUMP DONT WORK? CHECK FUSE 24 .IT IS A 2O AMPS FUSE AT THE FUSE HOLDER LOOKING LIKE THIS..

the wiring on the back of the column switch may have broken off check that first common prob

usaully located at the bottom of washer tank where you fill the window washer fluid some have fuses in the fuse box others the wires corrode or break at the pump or pump burnt

The wiring diagrams in the Haynes book should show the washer pump circuit? Often the washer pump shares the same fuse as the wipers.
You could pull off the electrical connector for the washer switch, or the multi-function switch if so equipped, and check for voltage on the pump wire going to the switch, key on. Then check if power going out of switch to the pump-key on and pump switch on. If power on both, the wire from switch to pump must be broken. Run a new wire. If power into switch but none out-switch is bad. If no power into switch for the pump, may have to keep looking for a bad fuse or the wire from fuse panel to the washer switch may have a problem. Hope this helps, good luck.

Check the fuse box for F9 blown fuse.

The washer pump relay is number 207 and is located in the main fuse box under the hood. A detailed fuse diagram can be found at https://automobilediagram.com/ford-f-150-fuse-box-diagram Hope this info helps!

In my experience i would say its the pump. But if you look in your owners manual there will be a fuse diagram. From there you can check the fuse. Also if you know where the fuse boxes are located you can look on the backside of the lid that closes the fuse box there is a diagram. That will help you locate the fuse. If you need further assistance please let me know. Thanks, Midwest-tek

the washer pump is located at the bottom of the washer fluid resivor,,,,,under the hood,you gotta remove the resivor to remove the pump
