On my dash it says to reset door adjar. What do I need to do I'm mechanically inclined

I don't think there is a reset for it. One of the door switches is not working. Push on all doors from outside car. The light will probably go off w/ at least one door being pushed. That will be the door with a bad switch.

a piece of black electrial tape is the cheap way to fix this or you can try unhooking the positive battery cable for a minute or so sometimes the resets the computer.
