I have the Infinity Sound System in my 2002 Jeep Cherokee/Liberty (European export) with radio/CD/cassette/rear CD changer. Recently I've noticed the radio and display do not turn on right away either with the key to acc. with the ignition turned before starting the engine, or the engine running; it usually takes anywhere from 3 to 10 minutes for the radio/display to turn on and sometimes it seems it will turn on faster if I start flipping through switches either on the radio or on the control stalk like headlamp, dash light dimmer, etc.
I can hear a clicking noise behind the steering wheel, (almost like a relay switch,) when I press the radio power button on, but the display stays off and the radio doesn't work. Interestingly, with the steering wheel controls I can switch to the rear CD player/changer input and that will start playing music and I can even change the volume with the power **** on the head unit, adjust fade/balance, etc. but again, nothing on the display turns on and the radio doesn't work.
When the radio/display does finally turn on I can start tuning to different stations and it will generally stay on when the car is running. However, sometimes if I use the seek button a lot, for example, it will turn back off randomly and it's possible this happens more while the engine isn't running (with the key to acc. or turned before starting) or maybe it just turns back off because the buttons are pushed too much like seek, etc.
Took off the trim panel and disconnected the radio from its two connections and antenna plug then reconnected to see if that would do something, also just to check the connections and state of the radio (without actually opening the unit), and I can't seem to see anything suspicious (again, I did not actually open the radio and look at circuit boards etc.)
I took a look at the side fuse box comparing it to this fuse box diagram and noticed that some fuses are the incorrect amperage, and some sockets that should have fuses are empty, and some sockets that should be empty according to the diagram have fuses in them. For example, the #21 "Radio, Body Control Module, Left/Right Door Lock Switch" that uses a 10 amp fuse, has no fuse actually in it. The #20, which on the diagram shows as empty, on mine has a 20 amp fuse, and the #22 "Power Sunroof Relay, Antenna Module" which should have a 20 amp fuse has a 10 amp fuse on mine, the #23 slot is empty on the diagram but has a 10 amp fuse on mine. I'm assuming that the fuse box diagram I'm using is correct, but perhaps I'm missing something with how fuses work, and maybe the fuses don't even have anything to do with my original problem.
Some other ideas I had: could there be something wrong witch a capacitor etc. in the radio itself? Maybe a problem with the antenna? A wiring issue or resistance somewhere?
Any help would be really appreciated. I would rather keep this radio and try to fix it or replace it with another used OEM that doesn't cost too much, rather than installing a new radio, if that's at all possible. Thank you.
