Are the infrared LEDs powered by the same 12 v as the camera, or perhaps they switched at dash with tail lights, or use a light sensor to turn on? Which ever way they are powered, it gives a starting point to find out the problem.
To see if the infrared LEDs are working, use the video feature of a phone to observe if the lights are on.
