Anyone know if the original window motors for these years are unique?

 

Looks like 84 to 86E use the same motors. So yes for 2 1/2 years

 

Looks like the 84-85 use a large 22 tooth gear. All motors sold now are 9 or 12. I think thats going to be a huge issue because the diameter is different.

 

From what I can see is 84 - 85 and 86 early use 12 tooth then 86L to 96 use the 9 tooth gear. Not sure how you are counting 22 teeth, you might want to research a little more. Or pull the old one out and compare, maybe someone changed yours. 22 teeth on the motor would make the window travel really fast. If it has 22 teeth see if it has a part # on it. Hope this helps

 

There are a few on ebay with 22 teeth also

 

Looks like you are unique, On Zip corvette parts they have an upgrade for 84 to 96 windows, It looks like that is what you have. the motor and tracks have been updated

 

Not sure how you figured that out but you are Wrong!

 

Well maybe. 22 teeth drives were an update for that time, looks like. That's all I got. good luck!

 

Any of you guys tried to rebuild the door motors

 

I know of no one that sells rebuild kits ( they call the motors nonserviceable item) Some gears are available. An easy fix if your final gears are good. Buy a stock (12 tooth) pull the gear assembly apart and put your 20 tooth assembly in its place. new motor new bushings if that is only problem. That might work
