Door ajar light comes on, interior lights flash continual pinging doors are all closed. any help would be appreciated

My interior lights come on and off, door locks on/off with door chime going off and on, door ajar idoit light coming on. I already replaced front door switches, rear door switch, sliding door contact, and now went to junkyard and will begin swapping relaysat the junction box under the dash by the steering wheel. I will let all know if a relay fixed the problem.
