92 Regal Power window regulator motor

92 Regal 4 door

Does anyone know if the power window regulator motors and or regulator assemblys are interchangeable from door to door???? I have not done any trouble shooting to date. Hope I don't need to remove door panels on both rear doors also to find out.

Mother in laws drivers side window does not work all the time and she cannot afford a new motor.

Thanks for any input.

I'm pretty sure they are different side to side. Best thing to do is call a parts store and see if they are the same part number.
