Rear window defrost issue

Hey guys,
Just bought a new toy, 04 Rubicon. It's got a couple issues, hoping you can help. I tried the FAQ area with no luck, also did a search and someone has had same problem, but was directed to a thread that doesn't load.

04Rubicon, all stock, auto.... My rear window defrost button is blinking the orange light, and the mirror compass flashes at the same time. Any ideas?

Also, the fog lights stay on, which I've pulled the relay and assume is the blinker assy problem.

Thanks

I just want to add, it has a hardtop, and it's the original factory one.

More info....
With jeep running, if I turn on my rear window defrost, my dome lights turn on as well as all my instrument lights. The whole dash lights up, brake, check eng, oil, seat belt, fuel, blinkers, airbag, ect....

If I turn the key on without starting and turn on the rear defrost, then everything turns off, as if the key is switched off.

This is crazy, need help.

This is just a guess but hopefully it's something this simple. There are some ground connections below the dash speakers on each side. Remove the two screws in each speaker cover, then pull the speaker covers towards the rear of the vehicle to remove them. Check the screws below the lower speaker screws are tight. If that doesn't help maybe the body ground needs checking under the hood.

Update
I pulled cluster, cleaned connectors, unplugged and checked ALL connectors under dash, cleaned grounds behind drivers speaker, went under hood and checked and cleaned all connectors, changed battery terminals due to corrosion.
Still have the same problem, PLUS, now my door chime "chimes" anytime my door is open, even with nothing on or keys in the ignition.

Is there any help out there? Thank you to one person who has given a tip.
This is a common issue, as it gets a lot of hits if googled, but no info on the fix.

It's certainly a strange problem and the first of this type that I've heard of. I'm wondering if the cluster is fried. The timer for the rear defrost is controlled by the cluster in all years. In later years the dash/cluster background illumination is controlled by the cluster - there are quite a few cases where the illumination fails due to a fault in the cluster. Chime, again, is controlled by the cluster.

It would be nice if you could pull your cluster and try it in a different 04 TJ. Not sure without checking FSMs what other years the cluster could be tried in. Checked now. 03-04 are the same in 05 there is an SCI receive input that is not on 03-04 model clusters but as it's for the OBDII port the cluster should be fine tried in 05-06 models too if you can find one local willing to let you test your cluster by swapping into their dash.

The switch for the key in place sensor is in the ignition itself. Either the ignition switch is a problem (key in place switch stuck closed) or the actuator between the tumbler and the ignition switch is activating it even with the key out.

I thought about that but with so much else going on cluster related I forgot to get back to that one. If the chime isn't down to a flaky cluster the only other things which will cause the same beeping as the key in and door open chime are, lights on with door open, or the turn signal left on for more than a mile at speeds greater than 15 mph warning.

Update...
I replaced my Multi Function Switch (blinker switch), and ignition switch. This fixed my fog lights always on problem, and door chime issue.
I still have the "turn on rear defrost and all electrical shuts off" problem.

I'm going to replace my instrument cluster, but have a question.
I'm told it has to be a 04-05 cluster, but this is a rubicon. Do all 04-05 clusters have the " lockers" lights in them, or do I need to find a "Rubicon" only cluster?

Since the rubicon was introduced for 03, all clusters from 03 (rubicon or not) should have the locker lights feature. The circuit boards have LEDs for all the indicator lights with t he exception of full beam so everything should function fine.

As already stated, the only difference between 03-04 clusters and 05-06 clusters is an extra wire going to the 05-06 which is designated SCI receive. I've found one reference to problems with a cluster swap where the person who did it did not have SKIM fitted but the donor vehicle must have because he got the SKIM light on, and the cluster test revealed a code stating "buS b1" meaning the cluster isn't seeing a message from the SKIM. Here's the thread with the detail.

http://www.jeepforum.com/forum/f9/in...-km-hr-347282/

Aside from that I can't think of any other problems that should be experienced with a cluster swap. I would expect 03-06 to work for you but without finding any threads regarding cluster swaps I can't confirm it. I'd hate for you to swap the cluster and it not fix your problems. It would be nice to find somebody in your area with an 04 to try a cluster swap.

Sounds to me like your rear defrost switch is shorting somewhere. Have you checked the switch itself?

I see you have a new thread asking about the clusters which says the radio goes off too which I don't think has been mentioned in this thread.

The radio doesn't (or shouldn't) share any common circuit with the cluster or rear defrost. It really makes me think this is some sort of screwy power issue like a bad ground as initially suggested, or some sort off corrosion in the inside of the PDC such that when the load from the rear demist is presented it robs power from the other circuits. I haven't suggested it already but I wonder if the battery could possibly be weak. Might be worth getting it tested just to rule it out.

Trying to solve two problems, which could clearly be related to each other, in separate threads? I call FOUL!

Sorry about the other thread, just figured someone who has had a cluster issue might offer some advice, but may never actually look at this thread.
The radio not working was something new I just noticed, as well as the rear wiper, it doesn't work either. This Jeep is new to me and I'm just getting started with it.
So as of today, I've took apart, inspected, and reconnected every connector under the hood and dash. I've cleaned every ground I could find, including the ones behind the speaker. I even twisted the pins to the cluster. The battery was new when I bought it, but the connectors had some corrosion, so I replaced them. Everything was very clean....
The connector to the top was connected, so I disconnected, and still have the problem with the rear defrost. So it's not an issue with the top.
I haven't checked the switch, but did clean the connector. I'll check it tomorrow, also going to check for power to the wiper motor.

Thanks for the info on the cluster, I do have a friend with a donor jeep, but his doesn't have the rear defrost or wiper motor. So I can't check mine in his, and I'm worried I might damage his if I install in mine. What do you think?
