Power Window Problems

George,

If you still have the plastic gear, that may have broken. Replacing it will require removal of the window regulator/motor assembly. The first part of the link below will explain how to remove the assembly.

Other possibilities are a bad switch, bad connection(s), or a bad ground.

save yourself a lot of hassle, just replace the motor with a tarus or aerostar unit. google for the instructions, it's cheap, easy and the replacement units work a lot faster than the originals.

Thanks for the tips guys. I'll look in to finding a replacement motor.

Does the motor have to be removed from the assembly before the assembly can be removed from the door?

No.

Then what is the trick to taking the whole assembly out? I tried on Sunday and couldn't get is out.

Thanks

It should come out through the large hole at the bottom of the door, as seen in the pic from the link above. You might have to reposition the glass lifting arm.

John

It can come out from the large hole below or above. I just re/re mine from above. As said, your may have to reposition the arm. Passenger side shot. You can see some of the grinding on the arm that was required to have the window sit 1" lower than factory.

Thanks guys...I'll give it a shot this weekend and let you know.

This page will guide you step-by-step for the removal http://www.panteraplace.com/page164.htm

Since you're now into the repair fairly deeply, I strongly recommend the upgrade to Taurus window motors explained in other posts. This is not a difficult job to do and makes a world of difference in the windows. Having done it on my car, I wouldn't even consider trying to fix the old system.

I agree. You are 50%, at least, into the conversion. Why anyone would replace gears is beyond me. You would still have inefficient motors. The Taurus motors are a fraction of the amps, newer, cheap and fast. You should be able to buy two Taurus motors for less than 1 brass gear. You end up with a dependable system. Just follow the directions. It is not a hard job!

Just wanted to add my experience for this.

In my case, I decided to do the Taurus motor conversion because I have the same problem (I suspect). My drivers-side window stopped going up all the way but would go down easily. After I changed the motor out and tested the new Taurus one with a 12v battery, everything worked great. BUT when I reconnect the car power it still doesn't work properly. Seems I've got a bad connection to or at the switch (only DS is affected).

Have you tried connecting good power direct to your factory motors to see if they work? Turns out my original motor was completely fine (although slow as stock ones are) and didn't need replacing. I'm glad I did change it, however because it sure is a LOT faster now. I also did the lowering mod which is a piece of cake and much easier than it looks. It's also a lot easier than changing out the motors is, IMO.

The window switches are not a very good design in that there is no wipe on the contacts as they close. New switches should fix you up for a few years.

The window switches would work much better if there were relays involved or a controller like this was used http://www.panteraplace.com/page219.htm .

Mike

You're right about that Mike, assuming you're referring to the Bosch ones.

After I changed my window motor I tested my switch. Even though I had replaced them only a few years ago, it turned out that the drivers-side one was shot. It must have all of 100 actuations on it.

My car got about 35 years out of the originals and maybe 3 years out of the Bosch ones. I'm pretty disappointed. With all the crap people give Pantera electrics it turns out the fancy German stuff is real garbage by comparison. I guess they are meant to work only with relays for the load.

So, if any of you have Bosch switches and your windows are slow (or won't go all the way up), don't assume it's not the switch. Check that first.

Here's an update. I got the whole thing out yesterday and found 30 year old grease binding everything up. I got it all cleaned up and put on fresh white grease to the whole assembly. I re-installed it and did not connect the window to the arm. It worked fine in the middle range, but not from fully closed or fully open. So it looks like not I will do the whole motor conversion. I better hurry up and get it done. It is by the way the passenger side door and my wife wants to go riding sometime this summer.

Wish me luck!

George

Goerge,

I'm sure it will go well. If it's any help, I have photos of what I did to mine at the bottom of this web page:

Cheers,
Mark

Thanks Mark.


I'll check it out!

George

Well,
I jumpered directly from the battery to the motor with the same results. It wants to start moving but gets hung up in either direction. Starting to prepare for the motor upgrade.

Wish me luck again!

Thanks for all your help!

George

Got to get ready for the NE Exotic show on the 21st. Hope some of you others can make it. See Larry W's post earlier last month.

I did the Taurus window motor upgrade to my driver side window last week. Works awesome!

What is the reasoning behind enuring I get the motor with 4 holes for mounting if I'm only going to use three of them and shim the 4th?
