Narrative:
In the weather on a heading to intercept [runway] 35C localizer; during turn onto localizer; localizer signal failed. Pilot flying (PF) overturned localizer and started correcting. RAPCON; gave a correction and localizer came back. Localizer failed again as we were intercepting for a second time. Localizer continued to fail 3-4 times causing us to weave left and right on final. At about 5-6 miles we stabilized; finished the approach and landed uneventfully.
