Try turning it by hand with a socket over the crankshaft damper bolt and use a breaker bar.

A motor that is locked up cannot make a rotation. The motor will not turn over or start. Try to turn the main pulley. When the pulley cannot be by just, the motor is locked up.

Remove all the spark plugs. If you cannot turn the engine over by hand with a socket & ratchet, it is locked up.

As far as I know, there was a recall regarding the washer fluid motor.

You need to first know the wattage of the motor and locked rotor current can be tested at a lab only
