How do i get my advance lever to move it seems jammed
A Canon AE-1 is not an EOS camera the Canon "A" series is manual focus while EOS is auto focus. First thought In answer to the advance lever stuck or jammed I'm going to assume the camera is in serviceable condition and has not been subjected to water damage or harsh use. If we are dealing with just the advance lever then I'd say that you have over advanced the film at the last frame. I've done this myself after loading a 24 exposure and thinking I had a 36 exposure film. At the bottom of the camera there is a little pin which releases the advance lever and allows the user to rewind the film. Under normal conditions when it's time to rewind the film into the canister this pin offers little resistance to pushing in to release, however depending on how much force the advance lever has been subjected to increases the tension on this pin. Push the pin in and rewind the film.
Second thought is if you have film in the camera and it has not been used fully then it's possible that the film has already been advanced to a new frame and the shutter needs to be activated before the lever will become free and advance to the next frame.
Other problems with the Canon "A" series cameras is they have a tendency to dry out the lubrication and begin to squeak when the shutter is fired. This condition can eventually result is a shutter seizure and give the same advance lever condition.
Those are the three things that come to mind over this lever problem lets hope it's just run out of film.
