Put a pin down the jet hole a couple of times YOU know the HOLE IS NOW CLEAR, try pump,(If it fails to squirt )remove tailgate panel to get access to the washer pipe pull pipe off jet now operate pump till water flows (this clears gunge out of pipe) check where the pipe attaches the jet for gunge ,See if jet will come apart as there could be a {micro mesh filter inside} clean and replace,should now WORK. (I did this on a rear metro washer where i found the filter in the jet was blocked.)
