Electrical problem
2000 Dodge Ram V8 Four Wheel Drive Automatic 103000 miles

i was driving home and went to dim my dash lights when i did my dash lights, ash tray,and drink holder lights went out also my radio shut off. my radio came back on immediately but none of my lights came back on. i checked the fuses and they were all good. i also got a new switch and they still didnt work. i checked my bulbs too and they were all good. wondering if u may know what the problem is. thanks
