My Christmas guests are coming later today, and mostly this weekend. My family is all far away so I will travel to visit them in January. So, for my Christmas present to myself, I took the day to tackle the windows on Ole Blue, the 88 Lincoln. To recap, the window seals are so stiff, they grab the window and it keeps stripping the nylon gear in the motor (I thought). My plan was to fix the motor, and use a little grinding wheel in my Dremel Moto tool to open up the channel in the window seals. I hadn’t been in the door in a while, and I was thinking I might have to cut a couple holes in the inside metal panel to reach.
I got the door panel off in less than 10 minutes. (because I’ve done it 100 times). I was very pleasantly surprised to find out like 80% of the gasket was easily accessible.
I took the speaker out to get at the motor, and took the motor out, I opened up the gearbox, and the problem was not with the nylon gear. There are three bumpers that make a bump coupling between the drive mechanism and the final gear. Years ago, those bumpers, kind of like urethane plastic little cylinders, wore out. You can’t buy them, you can only buy the whole motor which isn’t cheap. And the door boaters for that four year run of town car, are no longer made, you can’t even find them rebuilt In a YouTube video I found out you can replace them by making bumpers by putting the right size vacuum tube over a short piece of steel. I’ve done that before on several vehicles, and I did that about three years ago to this one.

If you look at the second picture, you can see the steel centers laying on either side of the gear. On the bottom, the black mess on top of the worm gear is the bits of the vacuum tube that were ground into little bits. When I took it apart, and I cleaned it out, the vacuum tub rubber was not only broken up in little pieces, it was also mushy. I had used STP Molly grease when I rebuilt the motor, and I think the Molly grease helped to disintegrate the rubber on the vacuum tube.
I went into the ancient vacuum tube section of the shed of miracles, and I found a piece of ancient Mercedes rheum vacuum tubing that was almost as hard as a rock. I used that and I made the three bumpers.

I cleaned out all of the old grease and debris from inside that gearbox. Then I used spray lithium grease and bathed it, actually puddled it up in there.

Then I reassembled the motor, tested it, and it was dead.
I pulled one of the wires out of a crimp and didn’t notice it, probably when I was taking it out. Easy fix.
I placed it on a clean towel inside a pristine cigar box I had, to temporary hold the motor out of respect. The driver side window motor is different than the others, and different than other Fords, so they are like gold these days.
I then got into the door with the Dremel Moto tool.

It was pretty straightforward. I got the whole section of seal left of the main window, about 2/3 of the seal on the right side of the window, the whole side of the vent window on the left, and the whole side of the vent window on the right. In case you don’t remember or didn’t know, when you push the window button on the Town Cars the smoker’s window goes down, followed by the main window. And they go up the opposite, all with the one control.
Then I cleaned up the mess, and put the motor back in so I could run the window down. I did the same thing to all the seals above the door sill. Then I soaked them with the petroleum-free silicone spray.
When I had it all together, except for the door panel, I ran it up and down, and there is a dramatic difference in the performance. I don’t think I realized how hard it was binding until I saw it moving fairly freely.
When I put the door insulation back on, and I put the door panel back on, and I put all the switches together in the armrest, I really took my time and made sure I was using the right screws, and where they were loose, I went into the Lincoln interior screws section of the shed of miracles, got the next bigger or longer screw so it was all right and tight.
I walked around with a smile for the rest of the afternoon and evening. It’s been worrying me for a couple years. My guests don’t come till about six, so I’m going to tackle the passenger door, which is acting up, but hasn’t totally failed yet. Now that I know what I’m doing, I bet I can knock it out an hour and a half.
Merry Christmas folks
