How to disable the indicator beeping in my 05 Ford F-150 XL Triton?

I have problems with processing sound and little repetitive noises drive me insane. To be clear, the sound I'm referring to occurs when say the driver door is open with the keys still in the ignition without the truck running or when the seatbelt indicator is active. I'm afraid that if I do not disable this beeping that I will lose control and destroy my truck if I do not find the source of this incessant beeping and quiet it for good. Any leads or DIY instructions are welcomed!

You might just need to replace the door jam switch that makes the interior light come on as this also controls the ding, ding, ding, when the keys are in the ignition with the door open and or the seat belts are not fastened and so on. Even the radio shuts off on a Cadillac when you open the door with the ignition off by way of the same switch. When they get corroded, that switch, the contact is broken when it should be closed or the contact isn't broken when the door closes.
