#655 of 735 2012 Grand Cherokee battery light
Jun 12, 2012 (3:59 pm)
Appears that my Jeep does not like to go thru a automatic car wash, one where the vehical is pulled thru. Four out of 6 times I will have the wipers come on automatically and make 1 or 2 swipes, the traction (or hill??) light will flash, and then the battery light comes on a stays on. The first time I took it to the dealer and as soon as they shut it off and restarted the light was cleared. They kept it for 4 hours and just said that the codes indicated a voltage spike but no issues. Now I'm just keeping a log between oil changes to document.
Any ideas or similar experiences?

I found the problem when I got another reading that the sensor was bad the one I just changed out. I started pulling all the wires from that sensor all the way to the pcm and found a burnt wire back behind the motor. The bracket was broke that held them from touching the motor and that is why it happened. I never could get a good reading on the injectors that is why I figured it had to be a wire. Hope this helps someone. Now I am getting 2 different codes on the fans. Back to the drawing board. But it runs so good..Tanya

Ever since I got my Jeep, there have been slight electrical issues, but over the past 5 years they've gotten worse, and more of them. Now that I'm seriously considering getting rid of it (which I don't wanna do) I looked you guys up. Quick, ain't I? Anyhow, the automatic lights will just randomly start flashing. As soon as I touch the panel where the control dial is for the lights, it stops. If I don't use the automatic setting, and just turn them on manually, no flashing of the headlights. I live in the city so I like the automatics - I can get in the house before they shut off. But living in the city could also get me shot if they start flashing when I'm behind someone. My radio never worked right, so I replaced the antenna several years ago, didn't help. Now the CD player doesn't work either. Just barely static. My sunroof won't open anymore. Heated seats don't heat. And now I get a message at night that says my taillights aren't working, but they are. Till I get home from work, the message is usually gone. All the gauges work, windows, work, AC blower works, dash lighting works, security alarm works, power seats work, cruise works, just the freaky things mentioned above.
Does anyone know if there has been a recall for this problem? It seems like a grounding issue. I put a new battery in it last year and nothing got worse at that time. All these things were happening waaay before the new battery except the CD player, and I feel my son had something to do with that. Any words you can offer to direct me would be appreciated.
#658 of 735 The famous Jeep Electrical problems
Jul 13, 2012 (1:48 pm)
I am having the famous Jeep electrical problems again. I have a 2004 Grand Cherokee 4.0L, 103K miles. 3 months ago I had the exact same issues, pulled the boot between the door and found the black wire was broken. I spliced it back together and everything worked perfect until 4 days ago. I checked the black wire again and found my splice had pulled apart. I re-spliced it but this time the problems did not go away. I ran a continuity check on that black wire (and every wire) that goes through the door and found everything to be connected. So I took it to a shop and they double checked all the wiring and even put in a new control unit and still nothing. I have tried the unplugging the battery trick and again nothing. I am starting to run out of ideas here. The black wire was broken once and my splice fixed it. The second time my splice (as well as the mechanics) won't fix it and my mult-imeter reads full continuity all the way to where it is grounded in the engine compartment. I am pretty sure this isn't the BCU gone bad. Any ideas? I listed my symptoms below
-A/C compressor does not kick on
-ALL the windows are stuck up
-Airbag light is on
-Seatbelt light is on
-Dash lights are stuck on high with no dimming
-Horn does not work
-The info center does not read temp or anything else but the compass works
-Dome light will not turn off
That is about it. To me this all relates back to those wires running through the door but they were all triple checked and came out ok. Any ideas?

Thank you! My windows haven't worked for about a year now. I had previously tried looking at those wires, but I couldn't see anything. I settled on the PCM but let it be. Did a google search and found your post and checked again. It was the black wire on mine which broke completely in half. The orange wire was well on its way. I cut the orange stipped them both and crimped them with copper crimpers. Little electrical tape and everything works great. Thanks again!

#664 of 735 rear light sensing
Sep 27, 2012 (1:54 pm)
I have a 1998 jeep Grand Cherokee 5.9
I am having problems with rear light failure
1. all the lights are fully functional.
2. I need a schematic showing the wiring for the plugs p1 and p2 on the light sensing module and where the supply voltage is sourced and what the outputs end up feeding, they appear to be on P1-9 wire blu with black tracer
3. I know the module has U4791B comparators in it. The comparator outputs pins 3&5 are all 10.5 to 12v- I think this is coming from the module that the output feeds
4. I have cleaned all contact and the bulb measure about 1.0 ohm of resistance.
5 Can I eliminate this module form the system as it causes more problems than it cures.
I appreciate all assistance in advance
