I just need to know where the fuse is for the radio and CD outle

Do you know for a fact the cig lighter element is not the problem with the blown fuse ? Have you tried using the outlet for powering something else ?
And what is the make model and year ?

knock sensor error

It has spark and fuel when the fuse is blown too?

you might have burned a wire in two... but i bet that fuse blew

sure does !
I'd suggest some places to look , but I am not seeing a model or year designation.

When you over loaded the circuit you could have done much more than blew a fuse. 1 Unhook whatever wiring you jumped across the fuse panel, then replace with the original amp rated fuse. Test radio and ac to see if they're functional (if they are consider yourself lucky or blessed) if not you may need to get an electrical tester to check continuity or power between fuse block to radio and ac to see if any wiring has been damaged if its not you could have fried those components and will need to replace them.

CHECK THE ACC FUSE ITS PROBABLY BLEW TO...

Replace the blown fuse. Many of today's vehicles use one fuse for multiple electronic systems.

Hi Tim,

It may be because of the fuse being blown up. You will find the fuse box in the front or in the bannet. Please check for the same. The fuse box will contain all the fuses together. Remove them and check if the connectivity between the two ends are still there. If not, buy a new fuse and enjoy! :)

The fuse for the radio/CD/DVD is seperate from the AC/Heat. Open fuse box under hood on right. follow fuse schematic to ac fuse position (note there are two so if not one, then it is the other) use the fuse puller that is in the fuse box, then replace the fuse. Good luck.
