It could possibly be bad ground wires or weak altinator or bad voltage from your battery.
The cost of a Nissan Sentra clock varies slightly by the year of the car and retailer. As of 2014 the clocks range in price of 24.99 to 49.99.
lights on the radio and clock have gone off
What kind of flicker do you mean? I own an '05 Aveo (my first car) and I find that my running lights get dim, go back to full brightness, and repeat. My interior clock goes in and out too. Why I mention the clock is that when I did a little research, I found that the circuit for the clock and the headlights are connected. After checking it out, I found that when the lights are bright, the clock is out, and when the lights were dim, the clock was on. I don't know if this is your issue, but it could help.
Press and hold the clock button for at least 2 seconds. The hours on the clock will flash. Use either the Tune/FF-REv or Seek/Track button up or down arrow to adjust the hour up or down. Press the clock button again and the minutes on the display will start flashing. Repeat the process. When the clock has been set, press clock again and it will return (stop flashing.) It will return to normal clock display in 10 seconds, or you can press clock one more time and it will return to the regular display setting. These instructions are right out of the owner's manual.
