Good evening.

The chimes are part of the light control module.

You really cannot disconnect it at all. They are pre programmed into the module itself.

Do you mean the door ajar chime?

I found this information on the chimes.

There is no disabling it as there is no option in the Ford scan tool for this feature.

You could disconnect all the door latch wiring to the doors and that may or may not turn it off.

What is the issue with the chimes?
