CB Radio not working anymore?

I have a CB Radio in my 2003 S10, I used to have it spliced into an old cell phone cigarette lighter for it to run, well that broke and I use a iPhone charger anyways so I couldn't use the CB and listen to my music at the same time so I decided to hard-wire it into the fuse-box. Well I got it working and grounded and put it in the fuse for the cigarette lighter. Well I got it mounted and such and a day goes by, start my truck and since I drive on the highway decide to turn the CB on to listen to whatever chatter, I didn't work. I got to campus and I tried re-grounding it and tightening the wire on the ground and I switched which fuse it was in, and nothing. It worked perfectly yesterday! Only other thing I can think of is where I have my ground it was like 40 degrees this morning so could the cold effect that at all? I also checked the fuse in the CB's wires itself and it was not blown and tried a new fuse just to be sure and nothing. Any help would be appreciated!

This is going to sound weard but i had the same problum. Make shure the mike cord is pluged in and tighten the nut. This should work if it turns on and their is no sound.

# 2 Check the antenna wire in the back of the CB and in the antena and make shure it is all tight.
