When I open the door the lights do not work. I can manually push the "map lights" on on each door and they work find. Any suggestions? And no, I'm not electrically inclined!

The primary reason would be corrosion of the door jamb switches. These are mounted halfway up the A pillar on the hinge end of the opening.
Depending upon your model, there may be an ambient light sensor in the dash. If the outside light is above a threshold the courtesy lamps will not illuminate via the door switches. This is controlled by the CCM (Central Control Module), later referred to as the BCM.
There is also a delay timer module original part no. 10098435 ) located in front of the passenger side I/P and taped to main wire harness. It is about a 2" cube. If this relay/timer has failed the lights may not operate with the door switches but will operate with the manual ON feature, since that switch simply grounds the lamp.
