We were on the PAITN4 arrival into ORD and had just received a vector to intercept the LOC to 27R. I noticed that we did not have preview needles; so I knew that something wasn't right. So I started by checking to see how far away from the airport we were. We were within 30 miles; approximately 27NM from the runway. So I asked the FO to switch to green needles after verifying we had the correct frequency 111.75 set as the active frequency in NAV 1 and 2. Once he switched to green needles it was too late. We had already gone through the localizer course and had entered the arrival corridor for 27L. At this point I checked to see which approach was loaded in the FMS. It was the ILS to 27L. We started to correct back to the 27R course at which point the ATC controller told us to turn to 290 degrees to reintercept the localizer. A few seconds later she informed us that the localizer was out of service. The FO at this point claimed that he could not hear the Morse code on NAV2 to identify the localizer. We got vectored back into sequence and flew the RNAV/GPS to 27R without any event or risk of conflicting with other traffic.

CRJ-200 flight crew reported difficulty intercepting the ORD Runway 27R localizer due to a misprogrammed FMS. At the same moment; an issue with the airport's ILS system prevented them from reintercepting the localizer.
