If your 85' has the original window regulators, it is common for the plastic ribbon to break, which can cause the window to stop working.
Removing the door skin is not difficult, but takes some time and patience. I have replaced both regulators in my 86' with the newer style (a project I highly recommend if you are going to open the door up).
I started by removing the screw in the end of the door skin, and then the screws around the pull handle and then the screws along the bottom of the door skin. Then I had to lift the door skin off of the door and disconnect the electrical connectors.
To get to the window regulator you will need to remove the inner metal panel, which will require you to disconnect the metal rods that operate the door lock and release handles. It is not hard, but you need to go slow and label screws if you don't think you can remember where everything goes (I usually label everything).
The one trick I do have to do involves gettting the door skin back on. I can never get the door skin to slip over the lock/unlock manual control rod. I tie a piece of string to it and use the string to help pull it into proper position.
I have an extra window ribbon i can let you have for $15.
1. remove all the screws from the perimeter of the door panel.
remove the speaker surround.
2. pry the manual door lock plastic **** out of the groove it slides in.
3. undo the 2 screws in the door armrest hand pocket
4. gently pull the bottom of the door panel towards you, and then kind of rock it side to side moving in the up direction.
5. unclip the hatch switch wire.
6. unclip the door window switch and wiper connectors.
7. unclip the door lock and the light connectors.
8. remove the door panel.
A. on the bottom of the door there is a bolt and on the top of the door there is two bolts. on the inside of the door that faces the door panel, there is another one. un do them, but mark them first for location.
B. remove the plastic sheeting over the door gently. You have to re-use it.
C. remove the wire connector from one end of the motor, and wrestle the window regulator out of the door.
D. you may have to loosen the felt wipers to facilitate this.
Now you have to get creative.
1. there are 2 rivets at the end of the metal track, and these come out with a drill, 1/8" I think,
2. Then take out the bolt that holds the bushing in the track. slide out the old track.
3. slide in the new track and cut to size.
4. grease the slide with lithium grease, and add two pop rivets into the holes, and reinsert the bushing and bolt.
installation is the reverse of removal, except you have to align the window track back into the original position.
when reinstalling the door panel after all the plugs have been reconnected, I use a coat hanger piece about 5 inches long with a 90* end on it to help guide the manual door lock rod into position.
Go to Chevy before you start, and get 10 plastic bathtub nut-serts and replace them when you get the door panel off.

Not to hijack the thread but CoupeGuy mentions making sure you mark bolt positions. When my window goes up. it seems to go too far in the cab and doesnt hit the window gasket right. When the PO had the inside done, did the window guide get out of alignment when they tightened these bolts? Is there another adjustment?
Sorry about the hijack but it is relevent as one reason why you would take the door panel off.
i have the same problem on my 95. the window goes up farther than it is supposed to. and because of this it is hitting the body of the car on the side of the roof. the dealership says that it is a certain part but of course when i take the door panel off it is not that part. but it really sucks to have this problem. because the window has hit the side panel so much i have to get that top bar on my targa repainted. it has been like this since i got the car.

Your problem is the front window stop. Very common Do a search on it for instructions.
You are only going to find out when you follow the above directions and have a look see. I suspect you have been told what is broken and you can replace the ribbon or upgrade the window regulator available from forum vendor Corvette Recylers
No we dont know and wont know what the problem is until we get into the door but we cant afford to take it to a shop and have it done. I was hoping that someone on here would have done this process before and had pictures so i didnt have to resort to taking it to a shop. I am just afraid that if i do it on my own without some visual help that i will mess something up that will end up costing more than the part i might need to fix the problem.
Don't worry about this so much. My window motor in my 84 Corvette was very weak and I was able to change it and do everything myself. Prior to doing it I had NO car technical experience. Opening up the door is very simple, it just takes a screwdriver and some elbow grease. Start removing every screw you can find on the door panel, including the speaker, and everything will sort of fall into place. As things loosen up, you'll see where it's still being held on and you can remove those too. Quite easy, just remember where the screws went and take before pics if needed. Once you remove it and you can see into the door frame, you'll notice how straightforward and easy it is to understand how the window operates. You can buy another window motor and ribbon from MidAmerica or Eckler's if you need too, and replacement will be simple. Take a friend and a couple very basic tools, and you should be able to open that door in no time at all. Furthermore, once you're in there, I promise you that you'll find out why your window is not working. Even when I did this myself, detaching the window and removing the window motor and changing the ribbon was all easy and only required common sense. Don't bring it to auto body shop and be charged hundreds for this easy task. You'll feel good when it's done!

Thanks alot! Thats reassuring! How did you handle the pop rivets that everyone is talking about?
I paid $100 for just one regulator prior to this sale.
The replacement process takes about a full hour at most....and of course it is one of those things that after you complete it....you ask yourself why did you wait........it's that easy
There were no rivets to remove for me, my door panel has been taken apart many times. Only screws. Just drill out any rivets and replace them with some similar screws you find laying around the garage. Let us know how this project goes!
