I had the same problem with my 2005 Grand Limited. The dealer claimed they could not find the fault. So I wrote a letter to the Service Manager asking him if it would take an accident to happen before they would replace the switch. He rang me back and booked the car in immediately. They replaced the switch under warranty, ie the left hand stalk. Works perfectly now.But it is damned annoying having to keep taking the car back and forth so I was glad when the service manager had it fixed.

#679 of 708 1991 Jeep Starts, but alternator won't kick in. Alternator 1 month old by jlm72

This has been happening a few times. I replaced the alternator about a month ago. When I start the Jeep, it is running on battery, I have checked the belt, and things seem to be working. A few times I have but some lubricants around the moving parts, and the alt kicks in.
 
Don't know what the problem could be.

Many of the problems you're describing happened to me. I suggest you start with unhooking your battery for about 30 minutes to reset the PCM. If that fixes the issues it's just temporary. Open your driver door and you'll see a black rubber sleeve. Pull it from the door to expose the wires inside. If I had to guess there will be 1 or more of these wires either nearly severed or completely disconnected. Sometimes you have to look carefully as I didn't see the problem at first but 8 months later there it was. I used copper sleeves and electrical tape to fix mine. Took 5 minutes. Hope this helped. Good luck

#681 of 708 fan relay code 9481? by fisherman20

2007 flex fuel grand cherokee has a 9481 code that indicates a bad relay, but when I swap thr high relay with the low one, the code remains the same. Does this sound familiar?

This problem began as a intermittent roaring fan, like it was stuck on and sounded like I was just flooring it. Sometimes it would stop and sound normal, then it would do it again in a few days. Finally it just stays on all the time and the check engine light comes on and this is where the 9481 code comes from. An interesting twist to this problem is that when the check engine light comes on the left tail light assembly stops working, and when the check engine light goes out they work again. It sounds like a short of some type but that don't explain the constant fan.

#683 of 708 JGC "liftgate open" problem by mwolf9000

Jan 16, 2013 (3:53 pm)

The rear liftgate on my 2005 JGC closes properly but a "Liftgate Open" idiot message comes up on the dashboard info screen. And so all the interior lights stay on while I'm driving. Any solution?

The first thing I would look at is the liftgate close switch. One bad switch would cause all your problems. I have the older body stlye so I don't know where yours is, but I'm sure you could find that out. Next, given the history of wiring problems in jeeps, I would look into the wiring to the switch. Good luck.

I am getting these codes ( P0320 - P0340 ) when using a scanner to check the engine light. I have already ordered the new sensors seeing as they are quite inexpensive. Should I replace one at a time to see if one is causing them both? How easy are they to replace?

Here ya go . Watch cylinder head with 0331 casting . Just had to replace at 130,000 miles . Heater core blew too ! Yeah big bucks for both , big buck ! Blinkers also have a problem with the relay . Pneumatic openers for hood and rear hatch door are bad . Just a few things that are true of this vehicle . Seems the whole cooling heating system has issues from what I have read . New head gasket, new cylinder head, new heater core, new radiator , what else can go wrong ?
