Re: IML: 60 window motor question

Hi Clay,

The nice thing about DC motors is that they are easily reversible by just switching polarity. That's what the up/down switch does, it's a cross wired double pole/double throw switch. Notice that there are two wires going to the motor, not just one wire and ground. There is nothing wrong with the motor. You can move it one way manually because the mechanism is spring loaded, the other way you are going against the spring tension, kind of like your garage door opener. The good news is that if the motor now runs only one way it's OK. Your problem is in the wiring or a mechanical jam. CAUTION you can easily break or lose a finger if you inadvertently unscrew or release something while you are diagnosing the problem, those springs are potent. It's usually easier to work on the thing while the glass is up, so securely tie wrap the lift arm or other support in the up position if you feel you must remove the motor or drive, thus taking the load off the drive. Unless a track is off or the guides are worn, your problem sounds more electrical than mechanical. But be careful with that mechanism!

Regards, Ken Stephenson

Greeting fellow imperialists

I need an opinion as to what is wrong with the passenger side window on my 60 Custom.

  A year ago the window worked fine either with the switch on the passenger door or with the drivers side master switch.

The window then stopped working with the passenger door switch , but worked fine with the master switch.

This year it doesn't work with either switch.

After removing the door panel tonight I found an amazingly pristine inner door cavity,window motor ,wiring and well lubricated window track.

With my fingers I rotated the motor shaft (which moved easily) and moved the window to the down position.

  I then tried the master switch again.

The window shot up so fast that it startled me. Yet it won't go down unless I do it manually.

So I guess my question is Can a window motor be bad in one direction only?

Or do I have a wiring and or switches problem?.

I searched the archives but didn't see any information pertaining to a window working in one direction only.



                                 Thanks in advance
