Auto focus not working - Canon AE-1 Program

My AE 1 P will focus but not take picture when lens is switched to AF, in MF it will take picture.  I have 2 lens and works the same with either

Must be spam. AE-1 Program is not an AF camera.

Funny - i've had this camera for 15 years and it always worked  

 

While the AE-1Program was not an AF camera, Canon made 4 self-focusing FD mount lenses.

So would the body be the problem since it acts the same with either lens??

Which lens are you using? Please be specific with the name.

I used, and still have, an AE-1P.
While that is correct,

Before the FD mount was obsoleted by the EOS system, Canon built four autofocus lenses. Of these, only the FD 35-70mm f/4 AF was capable of autofocus on all FD cameras. The others, known as AC lenses, offered autofocus only on the T80 camera.

The FD 35-70mm f/4 AF contained an entirely independent autofocus system and was among the world's first autofocus zoom lenses (the Pentax ME F was the first[7] ). The autofocus system was activated by a button on the side of the lens, and involved no communication with the camera body. It was reasonably accurate with still subjects, but was too slow to be a practical solution for moving subjects such as sports.”
