Check the fuse marked courtesy lights or interior lights.

factory radio or not.? all modes fail, even CD? am and fm?
is the factory radio bricked asking for CODE?
there are 3 supplies and ground
power, is red wire aftermarket. (cigar fuse)
power factory is wht/blk wire, at conn, G22 pin 9 of radio.
memory wire. (dome fuse) white, pin 1.
dial lamp. (tail fuse) pin 2, purple.

only ground and red wire matter,
checking fuses, we test them , not just look.
XL-7
does radio attempt to scan stations, is dial alive? at all?
not working say nothing to me, unless toally 100 percent dead in al ways , i bet the back light works with parking lamps on?

tell more , get more...

fuse, called dome fuse is blown, or radio fuse.
fuses that look bad, are, fuses that look good, may be...........
check fuses with an ohmmeter, fuses that look good can have very tiny cracks and are not good, only an ohmmeter works, on fuses with 100% accuracy. (a volt meter works in circuit even better !!!)
Did you test the dome lamp to see if it really works?
pull it , put across 12v battery ,does it glow?
did you look at the radio. and see if it has its own inline fuse?
did you hot wire the radio power wire to see if the radio even works at all?
if you have DMM with voltmeter this is so very easy to trace.
ask.

Hi, Check fuses, check the ground.

Yes as Steve says, but check your handbooks & manuals folder first to see if the dealer left the code stuck inside the radio hand book firstly, if not then contact the dealer as Steve said, hope this helps

Check for blown fuses
