How do I replace a window motor on a 1999 plymouth grand voyager. I am no mechanic so please make it simple

Not a simple fix. You have to remove the door panel, switches, door handle just to get to the inside of the door. There you have to unbolt tracks, drill out rivets, to remove the regulator. Then drill out rivets that hold the motor to the regulator and replace it by bolting it back on. Would be best to take it to a glass shop they should not charge more than $60 to $75 to do it for you. Well worth the charge.
