Blend door motor rebuild??

Just wondering if there is a way to rebuild the blend door actuator.

Don't know if they can be rebuilt but there are two new ones available on ebay

I bought one and it had a date of 5/93. It did not look new either. When I asked the seller about the misrepresentation. He said it was New old stock. I don't know about you but New old stock is not new stock as advertized. I have not install the one I bought off ebay. I think, I'm going to try to rebuild the ircm first. thanks

The problem was the Ircm. I replaced the one I had and the blend door is working again.
