Good morning fellow forum members. My 2008 Humner H2 has a slight problem im hoping someone can help me with. My stereo and also my rear console display are very dim. They did not used to be that way, it just happened one day recently. The stereo and the rear console display still function as intended. However, I can't see anything on either screen unless it is very dark outside and no lights are on in the truck. If anyone can give me some information on a possible solution I would greatly appreciate it!!!!

 

I have a 2004 so I'm not familiar with what the 2nd row display looks like on an 08. Can you attach some pictures? The fact that both the front and rear went dim at the same time makes me think it isn't the head unit itself just dying and something else. Was any work done prior or did they just go dim all of a sudden randomly? I also have an aftermarket Kenwood so I don't use the factory head unit. Is there any sort of dimming setting that could've accidentally been changed? On 2 different occasions when I had a mysterious problem in my H3 my 3 year old had messed with a setting or pushed a button

 

Is it just the displays? Or are your dash lights dim as well? If the dash lights are dim as well then i would start with the dimmer dial that is beside your headlight switch and is all one unit and are not expensive or hard to replace. It is potentiometer and may be on its way out. Keep in mind that im not familiar with the 08 interior so it may be different.
