I have a 2011 ford escape and a replaced the rear wiper motor and 1 year later it has stopped working. When you turn on the switch it clicks and moves a few centimeters and stops. Please help.

 

Not always, but a good part of the time a poor connection will offer high resistance to the circuit and not enough power will be available for the motor to operate properly.

Also,,,,,,,,depending on where you obtained the replacement motor can have some bearing on it's dependability.
