There is lots of information on this web site about windshield shades. But I could not find any exact replacement motors for AutoMotion shades. I have located the motors at braddandhall.com. The part number is AMS EL-4280P-1230 Switched. If anyone needs any details on motor replacement email me at firstname.lastname@example.org
The most difficult part of this job was finding a motor that did not require modification.
