1997 Ford F-150 door chimes won't turn off

Electrical problem
1997 Ford F150 Two Wheel Drive Automatic 150000 miles

As soon as I put the keys in the ignition, whether the door is open or not, the door chimes start ringing. Can't get them to stop. They will randomly stop on their own after 1 - 30 mins, esp if car has been left in bright sunlight or warm day.

decoupling wiring underneath dash disables windshield wipers and fan.

o and while we're at it, just replaced thermostat but not getting heat or air conditioning.

help!
