Shop Manual Page 63 - 70 Avanti Power Window Wiring  Reg/Green = Lower Window Yellow/Green = Raise Window Black = +12V Power There is a White Ground wire ( not shown) on each motor to the a chassis ground. Out of the car  Note the spring, mounted in the pocket just above the motor. this spring winds UP as the window travels DOWN and eases the amount of power needed to raise it. An additional spring can be mounted on the outer scissor axis, noted by the slot in the pivot point. This can make life easier also.
Disassembled  Coupling that connects motor to transmission / Removing the 2 screws adjacent to the top of the motor flange will separate the two  This is a Bosch window motor, same as used on a Ford of the same year / They draw a lot of current and use 10 gauge wiring for power transmission through switches, etc.   This is the transmission, where a worm gear, coupled to the motor armature, turns a gear to actuate the regulator. The gear casiing here shows how compacted the grease will become after a lifetime of use. The increase of turning resistance here, will impart a strain on the motor and can cause it to burn out. By merely cleaning this small gearbox and adding fresh grease can make your windows act like new. Read the above section on the Ammeter draw indication. If the gauge swings full scale when operating the windows, it's time to clean this area.     Note the insulation chipping off the green wire and the red one behind. Likely due to heat and age. These motors draw 15-20 amps when operating and any compromise, unintentional ground or miswiring when assembling the system will fry a motor in a heartbeat. Be careful. Note: Along with the regulator transmission, take account of the plastic rollers that support the window and ease movement through the regulator guides. A bit of white Lithium grease here can make things work much easier also. Additional info (You do not have to remove the Vent window to get the motors and regulators out...)
