Jeep Cherokee Electrical Problems
Ok I have a dilema. My wifes jeep is a 95 jeep orvis. One night when we turned on the overhead light for the rear seat the radio shut off, and the little panel which shows picture of the vehicle would blink. The clock has always gone out on occasion for no apparent reason. Anyhow as soon as you open the door there is a ticking sound coming from passenger side dash. As soon as door is shut ticking stops. The radio is still out, and the heater wont kick on unless the door is shut. If you open the door the heater shuts off. I checked a few minutes ago and found the ticking to come from a relay that was under the glove compartment. I took out a few screws from glove compartment and saw a block with what looks like some relays. On the relay is 56006709 under that is 50732 and then a # under that that is pressed in probally for production #. When I take the relay out the ticking stops but then so does my lights up above. So I am wondering what this relay is and could that relay cause all this problems if it was blown. I have googled it all over and did find a couple things but it doesn't specifically say what it is. It has 5 prongs with the numbers next to each one as 30 85 87a 86 28...any help would be appreciated. My wife is driving me nuts, because "I turned the light on like she asked and caused this whole mess, its all MY fault" lol

In my case, it involves the fan continuing to run after I've parked and shut off the engine. I have to pop the hood, walk around and literally smack the plastic fuse box under the hood.
The culprit in my case is the same type of relay you mentioned. I'm staring at one right now, numbered 56006709 50732. Sometimes relays fail open, sometimes they fail closed. In this case, my fan relay sticks closed sometimes.
Time to replace it with a new relay. I'm not sure how difficult that will be, to find an identical part, but will be calling around to local auto parts stores.
I have exactly the same problem as you described in your April post but with a 1994 Jeep Larado Grand Cherok. Did you get to the bottom of this? I have ordered a replacement relay, but I will be surpirised if the relay is the problem. jhtjr

Any resolution to your problems? I have 95 Jeep with similar problems- same clicking with door open, heater stuck on. I tried replacing 56006709 under the glove box but this didn't help. I can drive the car with the relay pulled- but radio, computer, HVAC don't work.
thanks all for any info
I had a very similar problem with a 95 Grand Cherokee. It all started when turning off an overhead light. A relay near the passenger's feet was clicking rapidly when a door was open; radio worked intermittently; an aftermarket CD changer didn't work; info display in front of gear shift didn't work; interior lights blinked dimly, even when they should have been off; power door locks didn't work. The car drove fine, but the electrical system was going crazy. It turned out that this was all caused by one blown fuse.
Good luck!
I get up this morning to tackle the problem I started first with the Overhead console and removed it. The Light Assembly's were loose because a couple mountings were broken ( fixed with super glue and a small piece of jb weld, yep Jb weld works on plastic great), The backs of the light housing has wires on it that are exposed at the connectors and when the light was pressed it shorted out on the roof metal ( Used CardBoard and tape to cover the connections before replacing).
I found that the #8 fuse was blown (15A mini blade fuse) Replaced it with another 15a and the problem is fixed.
Hope this helps everyone who has this problem
I'm a chick & I fix my own [non-permissible content removed].
To find the failure top techs install a load in place of the fuse. The "short" simply turns the load on and then the tech can follow the current flowing in the circuit with a tool like a low amps current probe right to the failure.
You could try inspecting the wiring harness to the neutral switch for abrasion and grounding, and the same could be done with the heated seat circuits. That method of finding the problem is labor intensive and you likely be looking at more places where the fault isn't than you will care to. If necessary an electronics specialist will make easy work of locating the failure.
Last Spring I bogged out my 2004 Jeep Grand Cherokee Limited and flooded the inside a little. After getting pulled out...and going up a hill, radio went dead and started having some electrical issues (Radio and CD exchanger did not want to play right, Back wiper would not shut off (even when I pulled the fuse under the dash out). The battery kept going dead and would not hold charge. Had the Alternator checked and was fine and changed the battery. the Battery went dead after sitting for alike 10 days without being started, jumped it and since then I make sure it gets started and runs for a bit every few days. Think it could be the Power amp for the radio/CD changer in the back, but think it could be something else like a major fuse under the hood. Any suggestions on what more to check?
