Check to see if your aux line is still connected to the aux ignition wire. this is needed for synchronization when you turn on your park light. if this isn't connected or has come apart, you will experience this problem. also, if the in dash has experienced extreme heat during loud play, you could have experienced a burnout. this is also common when over driving the dash device. im hoping its the first problem.

Assuming you do not have a dimming wire (orange or orange/white) connected, it sounds to me like the display lighting is out. Small bulbs might be able to be replaced if you can find the parts and are technically inclined. If not, I'd suggest looking for a replacement face at pacparts.com or buying a new radio. Probably a new radio because the face will most likely cost more than the entire radio.

I have a 1991 ford festiva i changed my radio and now my shifter and my dash lits dont work are they wired in with the factery radio


Hi, the factory radio uses the illumination wire, but the aftermarket radio does not. You have to make sure that wire is taped off so it doesn't short the illumination circuit. Check your tail lights fuse. If it's blown, pull the head unit and disconnect/tape off the illumination wire (blue with a white stripe) from the factory harness. Then put in a fresh fuse. If you have more questions, please specify the model of the head unit.

Disc can eject and be inserted but display does not light up, none of the buttons do anything. tried a different deck and it does the same thing the display dosen't work and no music plays. i am thinking...


It sounds like they messed up your installation. You can confirm their work by verifying that each wire was attached properly.

Click on this link for a PDF of the installation instructions of the radio (If you don't have the installation guide that came with the radio).

Illumination is the grey wire from the car to the orange with white stripe from the radio.

I suspect that the yellow wire from the car is not connected properly. When the orange wire (constant power from the car) is attached, but not the yellow wire you can insert and eject cds, but it will not turn on. Constant power is used for maintaining the clock and preset radio stations.

If everything looks correct, I would take your car back to the installer and have them correct the issue.

No back light on display


I know that most Clarions have an "illumination" wire usually orange and or orange/white. If the unit only has one, then most likely it is for a "dimmer circuit" and not atraight illumination. Let me know. If by putting power on tat orange wire does not do it, then you have a bad "bulb" in the faceplate.

Illumination v. Dimmer


Good day,

The illum wire goes directly to the headlight switch and tells it when to light up, where as the dimmer wire is variable meaning it would dim up or down with your dash light control. Dimmmer is usually only need on factory radio's and not aftermarket. I suggest wiring only to the illuum lead and do not connect dim. Also about the clock make sure your red and yellow wires are not crossed, yellow is a constant hot and red is only hot when the ignition is on, so if they are backwards the radio would loose it's memory when you turn the key off.

Hope this helps

Illumination not working when faceplate is open.


Wire braid out to the faceplate has got a parcially broken wire on it. Sony referes to it as a flexible circuit board. Part can be purchased from sony directly, an on a one to 10 scale to replace about a five.But it does involve taking your radio apart. So if you are handy at electronics. you can look it over. If you have doubts let a professional do it.
