When I open my driverdoor on my 2002 dodge ram sport 1500 the interior lights do not come on but when i open the other doors they do. I know there is a switch but do they tend to go bad and are they hard to replace or is this something else?

The door ajar switches are integral to the door latches on each door. The switches close a path to ground for the Instrument Cluster when a door is opened.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be replaced.

New from Dodge. Regular cab part # 55372843AA cost about $87.00
Quad cab part # 55372851AA cost about $36.00. Is a pretty simple fix. The only hard part is getting it out from around the window track. It takes some patience. Hope this helps....
thanks wow thats not bad i figured it would be something like the price of the reg cab. Now just the way it works is the "signal" is transfered from the cab to the door latch through the door and then somehow a wire picks it up and transfers it to the computer? Or is there a wire that runs off the latch itself?
If the switch provides a path to ground to complete a circuit, I presume the switch is a "normally open type"( with door closed) & closes the connection when the door opens. If that is the case can't I simply unplug the wiring connector to achieve "permanently open" status? I have a thumb wheel that does - 1. everything off no matter what, 2. door activated, 3. on until I dial back the thumb switch. I dont want to pay $87 for another crappy normally open switch
