i have removed the dash from my lexus is200 to change the interior lights to blue but in this process for some reason the lights do not work even when the original lights were put back in, all the other lights on the interior work besides the dials? can anyone help please? thanks

if the heater/ac lights have also gone out it means the gauge lighting fuse has been blown this is located in a little panel nr the acc pedal n is labled guage or somin

top man its was as you said was the fuse blown but not the gauge but the first one near the accerlation pedal!
