Dash lights out

Just noticed tonight that my dash lights are out. In specific it is only the rpm and speedometer lights. Any ideas on what to check or how to check them. I am by no means a car guy so if it's better for me to take to the dealership let me know.

Went out today and I washed the vehicle but I do not think that is related. About 2 weeks ago I had a new radio head unit put in not sure if something was wiggled loose from the install.

Any help/ideas would be appreciated!

 

you could just need the bulbs behind the gauge panel replaced, which would be my first step since ALL the lights aren't out. Could be a good opportunity to switch to a new color if you want. I shouldn't think it has much to do with the head unit unless they got fried when (if) the HU was spliced into the dimmer circuit.

 

Scratch that I pulled a fuse and then the dimmer dial started working and controlling again. Not sure if I knocked something loose and hit the dimmer today

Feel like and idiot now lol

 

at least it's fixed!
