The first thing to do is find out if it's the motor or the tubing. Often
times the tubing gets old and brittle, and breaks off. It could even be
pinched. Have someone push the switch for the washer and listen for the
motor. If you hear it, then look for where the washer fluid is going.
If it's the motor that's not working, you can test two ways. Put a volt
meter on the leads and push the switch for the fluid. If you have voltage,
then the problem is the motor. You could also send 12vdc directly to the
motor and see if it works.
Either way, if the motor's ok, then you need to look at either a fuse or the
washer switch itself. I guess it could even be a wiring problem.
You could also send 12vdc directly to the motor with clip leads and test it
