I just had my head unit installed and also noticed my dash lights dont work. I have not used them in over a week, so I dont know if it is something the stereo shop caused, or something that happened and I just noticed. The dash lights work, but only if I click the switch in the dome light position. When they are in the dimmer position, they do not work at all. So right now I am driving around with no dome light bulb, just so I can use the bright dash lights. Anyone ever had this problem? Do you think it is something the stereo shop could have done? I dont really want to take it back to the shop, cause I know they are not going to do anything about it. My Dad seems to think it is the switch itself, but it works in the dome light position, so I am frustrated and stumped. Thanks in advance.
