The dash speaker on the front passenger side is not working and it's more apparent that it's not working when using an ipod through the aux input then the radio. The car is an 06 ex sedan with navigation. I have only had the car for a couple of months and didn't notice it until recently. The cars cigarette lighter fuse for the output in the dash was blown but the one in the console was not. I replaced the fuse and the cigarette lighter has worked fine ever since. I don't know if that has anything to do with the speaker issue i am currently having. What should i do first to troubleshoot the speaker issue? Thanks in advance
