#449 of 708 Radio only works intermittently- what's could cause this?
Jan 10, 2011 (12:43 am)
I have a 1995 Jeep Grand Cherokee Laredo that has been in my immediate family since it was new. It originally came with the Infinity Gold AM/FM stereo w/ cassette with graphic equalizer and power antenna. It also has an amp located underneath the bottom cushion of the back seat on the driver's side. When it was about two years old, it the head unit was swapped out with the Infinity Gold AM/FM CD...my mom had worn out all her Anne Murray and ONJ cassettes, I think! =)
It all worked fine until 2006, when the radio would suddenly go silent for a few minutes once in a while. For a long time it only happened once or twice per month. My dad had inherited at this point (he gets mom's hand-me-downs) and when the problem got worse and started happening for longer periods and more frequently, he bought a new head unit for $50 off Ebay thinking that might fix the problem. It had no effect on the issue and it soon became more common for the radio not to work when you started the engine.
The CD player doesn't work but it always shows PLAY or PAUSE and I hear static/hissing from the speakers. Hitting the EJECT button will get rid of the PLAY/PAUSE indicator and sometimes the radio will work after doing this. If it doesn't start working, turning the headlights on/off, using a turn signal or switching the radio on and off will do the trick???
I have no idea where to begin looking for the source of the problem, but I really would .like to fix it. I use the Jeep as a second vehicle and drive it mostly on weekends, but I hate driving without a radio...not that I don't love hearing all the ruckus that the good ol' 4.0L makes, but no stereo could totally drown it out! =)
Any suggestions where to start troubleshooting or what the problem could be? Could it be related to the amp or ??? Any advice or info would be greatly appreciated! =)

your post on the 6th; in the morning before you try to start the jeep, see if your alternator is hot, if it is sucking the juice from your battery.

Hello and apologies for taking so long to reply. I have looked through my papers and have many to be sure but I cant find one with the harness part numbers. I think the dealer may still have it but as i recall it was the main harness in front of the firewall and the main ignition harness behind the firewall. I believe these harnesses are the only ones that directly relate to the ignition and instrument cluster. if i find anything further i will post a message.
PS, as I recall the dealership had finally covered the cost of this repair as I had spent over $2100 on a series of "modules" and switches. I was so happy that it was finally fixed that when I picked up the Jeep I dont think I did what I should have done and asked for all copies of paperwork.
#452 of 708 Illumination around Vent knob
Jan 25, 2011 (7:29 am)
Hello, One of the vent knobs stopped illuminating. I have a 2005 Jeep GC and just below the radio are 3 knobs for Fan, Temperature and Vent direction. The first two still have a light around them but the third doesn't anymore. Is this something, as a novice, can fix myself or should I have the mechanic look at it? What is entailed? Thank You for your help, Joe D

I had a similar issue. The knobs that control the air and heater went dim. The dealership replaced that entire console. It was expensive. I know this is something I could not have handled on my own.

I have a 2000 GCL that starts then stalls in 3 to 4 seconds. Changed battery, changed ignition switch, cleaned terminals at all plugs, added a extra ground from chassis to head.
What else should i try ? crank positioning sensor or disconnect alarm sys.?

I jnow it's been a couple years but did you resolve the electrical problem with your jeep where the controls on the drivers door for the windows, locks and side mirrors weren't working?

I was able to figure out the problem. There was a wire in the driver side door harness behind the fire wall as well (??) that had broke, due to wear and tear (says the Dealership). The manufactuer didn't help pay to fix it. I don't see how it was wear and tear, but it cost me about $300 to fix it, nothing major, but a pain in the you know what.
The shop had to sauder (spelling) the wire back together, instead of replacing the entire wire harness (which would have cost about $2K). Hopefully no more issues with it!
#457 of 708 Ignition Switch Problum.
Jan 30, 2011 (8:13 pm)
I own a WJ 2001 grand jeep cherokee,4.7L The problum that i got is the heater, and the heating seats, will not turn off when the key is in the off position and removed, you can turn them off manually, and after a few days the battery is dead, i have done some research on this from other Forums, they say that the Ignition Switch is at falt, and to cheak the blower motor, resistor,and wires. At the present time i am using the vehicle storeage information.Disconnect the IOD connector you open your hood and pull fuse at slot-15 and put in slot-11, until you find out where the problum is. When you fix the problum put this fuse back in slot-15. It turns off some of the power inside the vehicle, 1-radio 2-heater 3-heating seats,and other things. vehicle is ok to drive in the right weather, check all lights before moving. Do anybody have a problum like this.

Yes. The problem was a broken wire on the drivers side door. You need to open the conduit and check all the wires within this harness. Once you see where the harness is located, it will be easy to find. Look for a break, crack or kink.
