86 T-BIRD WINDOW MOTORS HOW TO REPLACE?

1986 Ford Thunderbird

Seems that my windows are having trouble going up and down. Are the motors easy to replace?
Do I need any special tools. Looks like there are `rivets` that have to be removed and will the motor come out somehow?

Pretty sure they are held in the doors with 1/4 inch rivets, so unless you have a gun capable, might not want to DIY. Old ones need to be drilled out and once th ereg is out, it needs to be locked down because it is spring loaded and WILL HURT YOU if not properly handled

I guess that " discretion is the better part of vallor" in all cases.
Great to get a good reply!

Thanks again

If you hear the motors, and they make noise when you press the button, it is probably not the motors that are failing, but broken bushings within them. I've heard it is a common problem in Ford cars. I went online and bought a new set of bushings when mine died, and when I went to install it, I found that it really isn't necessary (or reliable) to replace the bushings with expensive OEM parts.

I've never seen anything like it before, but because two gears within the motor do not fit together, Ford puts three bushings in between the gears in order to fill the gaps (they are two triangular gears of very different sizes). You could fill the gaps with three small nuts of similar size, and have no loss of performance. Also it would last much longer.

In reference to my image, the blue triangle is where the smaller gear should fit in, and the green circles are where the bushings go. It isn't very clear on the picture, but there is a larger triangle on the larger gear, which everything fits into. (I apologise for the quality of the image, but given my amount of time, I could only use my cell phone).

Assuming you haven't yet checked it out, you'll find that the motor is attached via hex nuts to a plate attaced to the door body via rivets. (You can't see the hex nuts because they are on the inside of the door.) You can take the motor off the plate, but you can't take the plate off of the door body. In oder to remove the motor/gear assembly you will have to take your speakers out.

BTW if you want to, they sell gear repair kits on ebay complete with the large gear (the one in my picture), but usually the gears are not broken, only the bushings (which you can replace with nuts for greater durability).

Please let me know if this information helps at all, it is relavent to my 1991 Thunderbird.

EDIT: BTW, I know this BECAUSE I have fixed both windows in my T-Bird
