Auto focus will not work on lenses with swm

The auto focus will not work with any lens that has the focus motor built into the lens. It works fine with lenses that use the focus motor built into the camera body. All switches on camera body and lenses are in the correct position, contacts on lenses and body have been cleaned with CRC QD Electronic Cleaner and the focusing system works perfectly when theses lenses are tried on another camera body.

I am a retired electronics engineer so have a lot of experience in electronics repair.

Is it worth replacing the autofocus module in the camera or does anyone have any other suggestions?
