My back light stopped working all of a sudden on my mileage indicator. Is there a fuse for this or is the light burnt out?

 

there is a bulb, if all the other lights or on it isn't the fuse. It's a number 24 bulb

 

i have the same problem too. But mine more wierd, when the 1st time starts my car there is no light and after several minutes like 10-15 minutes. the lights came back on. i opened the gauge cluster aand change with blue bulb your bulb with blue color. now everything is fine. the bulb size is 24 get it from autolumination.com.

 

Sorry, I'm a noob and since I can't make my own topic, I have to semi-hijack this thread. I have a '03 SE with the digital thermostat (titanium edition) and the left side is dark at night. The controls still work, but just not lit up. The display and right side are still fine. I recently installed a new Pioneer HU and this problem happened shortly thereafter. Dealership tells me you have to replace the entire unit and can't just replace the bulb - $380 rip off. Anyone know if you can take this thing apart to get to the bulb? If so, what kind of bulb is it? Thanks.
