Yes, push on the wiper motor. Alternatively, tug up on one of the wiper arms in your photo. That will move the linkage and motor. The most common cause of this problem is an arced ground strap on the motor, and just moving it slightly will momentarily get it going. If it does, there is a simple fix. You can almost get the motor to run temporarily by staring at it hard enough!
When the motor is easily accessible, you can also measure the voltage on the metal case of it. If there is any voltage when the wiper switch is on, that ground strap needs to be repaired.
If moving the motor doesn't work, we'll need to do some voltage measurements to solve the problem.
