okay so the other day while in my car the ac, radio, brake lights, dashboard and cigarette lighter all went out at the same time. I have had the fuses checked and none if them are blown. Can someone please help me

 

Sounds like your alternator is on it's way out. Have it checked.

 

I recently had it replaced but it was a used one

 

Have it checked with the car running, and a second test with the car running and all accessories on (a/c, headlights, stereo etc) and see if it passes.

It should read higher than 12.5V to 13.0V at all times, minimum.

 

OK I will check
