Let me try to understand what it is exactly that your asking. 1/ you had a light in the ceiling that was switched by the door. right? 2/ your trying to install a fan and a light combination in the same location. right? 3/ you would like to have one switch operate both the fan and the light at the same time. right? 4/ your fan and light combo comes with several pull chains. right? 5/ The wall switch is wired with a single hot lead usually 120v wire and is usually black (however make sure you turn the power off before attempting to work on any electrical wiring.). Test the wire at the switch and determine which side of the switch is hot, comming from the main breaker system in the house. That wire is your incomming hot lead wire. The wire that is on the other side of the switch goes to the light/fan and connects to the black wire (or Hot) side of the fan/light. Next find the neutral (white)wire. Test it to make sure it is not hot (120v). Then connect it to the fan/light. 6/ Now turn on the power and see if the fan/light work. If not pull the pull chains. If they still do not work then test the hot lead at the fan/light for 120v with the switch on. If you do not have power there then either the switch is bad or the wiring is broken where you hooked it to the fan/light.
