Metal touched inside the car lighter and the radio doesn't function

checked or tested with a test light? normally there are 2 fuses for the radio>>one switched and one hot at all times!

https://carmanuals2.com/acura/rl-2000-3-5-owner-s-manual-31856 (See pages 290 & 291 in this 'FREE' Owners Manual) ALL of the fuse locations and functions are in the manual... With illustrations! .. There 'IS AT LEAST' 1 blown fuse, you can rest assured of that, just need to find the failed fuse(s) using a test light, as suggested! *IF* you still have no luck >> http://repairpal.com/repair-shops
