Troubleshoot lose of power to red room lights. Garage switch bringing power to basement rec room was flipped off. The rec room was wired improperly originally so we informed her we could redo the wiring but she was not interested in that at this time. Voltages and connections were checked. Dimmer switch was checked and reinstalled and all lights are working inside the rec room. Homeowner was made aware that the garage switch needs to be on to make the switch work and that it is a temporary fix.
