EXTERIOR LIGHTING

The Lighting Control Module has failed and my brake lights and dash board lights turn off after couple minutes while driving with the lights on. I took my vehicle in to dealer already once for problem to be fixed a year ago. They did repair but now same problem is occurring again. I went back to dealer Sunrise Ford in Fontana and they said recall work is only warranty for 1 year or 12k miles. The work was done in December 2023. They want to charge me $230.00 for diagnostic. But issue is same problem as before. Recall number is 15S39. Driving without brake lights is dangerous and has limited my driving. I cannot go out at night. I do not have another vehicle. This affects my life. I've called other dealers and they refuse to do the work.
