Question about 2006 Hyundai Sonata
I have the same issue. It seems to happen to the lights when i am braking and it shifts into 2nd and 1st gear. The radio and A/C will both turn off together if both running together for a bout 3 to 5 seconds then come back on. I've noticed sometimes when i use the blinker the radio and A/C will do this then. I don't know if it is a coincidence or related. Has anyone figured out what causes this or how it can be resolved.
Your issues has more than one cause. The shifting into 2nd and 1st are separate to the radio & A/C. The blinker circuit is ALSO separate to the radio and A/C. The electrical system needs to be diagnosed, starting with the battery & charging system... Then look for any bad gound circuits/cables... starting with the battery, then chassis, then any individual power components (TCM, A/C, Lights, blinkers, A/C blower motor & controls, etc.)
