Help needed 1969 Plymouth

I have worked 2 months on the power windows New motors all switches checked ordered shop manual and the windows still will not work Hot to the switches but they will not work. Any help?Lee Waldren fORT mYERS, fL.

Remove old grease from linkages, pulleys, bearings, anything else that rotates. ???

Does the motor work with switches without being connected to windows?

Are the gears in the window motors nylon? Nylon gears will develop flat spots and "stick" to each other if they are not used regularly. A simple fix is to hold the switch in the direction you want the window to go and give the door a rap with a rubber mallet next to the window motor. This will usually break the gears loose. Cycle the window up and down several times. Repeat as often as is practical, particularly on windows which get less use.

Thank you. The window works fine with a direct power line to the new motor. Reverse the ground and it goes down or up but when the switch is installed nothing. I had the switches checked and they are fine. The manual shows a ground but I'm having trouble following it to its source.

Thanks to everyone helping me. Lee

Lee, my 1969 National Service data manual has these trouble shooting hints

All windows inoperable from all switches-circuit breaker or feed to circuit breaker faulty. Control relay faulty.

There are two wiring diagrams shown in the book. They are model dependent. What model do you have?

Lee, it looks like the main power feed and ground are located in the master switch panel controller on the drivers side door. The Nat Service book shows the main ground wire as a white-black wire going to the controller. Main power to the window is white-tan wire. The white tan wire should be the output side of the power window circuit breaker located on the fuse box under the dash.

I also have a 1970 Ply shop manual. It shows the power wire as tan and the ground as black, so it's similar at least in colors. The 1970 manual says the ground wire is connected to a screw on the cowl. That is the only ground for the controls so it has to make a good connection for everything to work.

I hope this is of some help. Let me know if you have any questions.

Could also be damaged wires where they bend as a result of the the doors opening and closing. Or corrosion in the junction boxes where the separate wire looms are connected together.
