Hi! It sound to me that you have an issue with the daytime running light system. This will have to be diagnosed by a qualified technician unfortunately. During the sunny times of the day, the I/p and dash illumination lights should come on in a bright mode for proper vision. This is obviously not happening. You may have something as simple as a faulty ambient light sensor (which is most likely the cause). This is the one on the dash in which you are covering. If it's not able to see / sense the correct light, it tells the daytime running light module it dark out, thus not switching to bright mode. Have that sensor checked via a scan tool to see id the reading change when sunny out as opposed to when the sensor is covered.
