After changing light-bulbs on my A/C unit and spliting two wires from the lighter in order to provide power for parking sensors control unit,I incidentally short circutied them. Later I found nothing except hazard light and TC switch working. Going through fuses, I realized 30A fuse in the engine compartment needed replacement, which I did. Still, neither A/C nor most of the switches (lighter included) are working. What did I do and how to fix it

will do so. thanks

no worries matey !!
