Could be the switch. Have you test the plug as you turn it on

 

 

Have you checked the fuse? If so do a power test at the fuse location.

 

 

On the washer pump, test for voltage between the blk/yel wire and a good ground (like any bare metal or the - battery post). If you get 0V when you turn on the washer from inside the car, then you know the issue is on the power side of the circuit.

Also, check the No 7 fuse in the driver's side interior fuse box. It is a 7.5 amp fuse. Use a volt meter or a test light to see if you have power on both posts on top of the fuse. Much quicker than pulling fuses. Key will have to be in the II position to test. See video below.

 

 

Actually it is not the wiper switch on the column because they washer and intermediate wipers still don’t no work

 

If changing the switch didn't work, then you're looking at a no power to the switch.

 

Where do I start with no power to the switch because the fuse is good and has power?
