I have a 99 grand cherokee 6cyl, had similar problem. Gauges bouncing, do you mean every gauge pegs to far side then goes to zero, maybe continues in this manner? That is the problem i had, also does any electronic overhead displays you have like miles per gallon, trip odometer(not the one in dash) all reset? If so, i think dealer was on right track with tightening battery posts, but when it happened again they should have replaced battery. When i had the problem i had noticed my battery gauge was reading 12.5 volts which i assumed was ok, it was in ok range of gauge, but a fully charged battery is actually 13.75 volts. Your jeep is 2006, battery is near end of life if original and may be low, good enough to start jeep, but the delicate computer acts weird with lower voltages and can cause a lot of strange electrical issues. When i replaced my battery 5 months ago, problems were all solved, so make sure your battery is closer to 14 volts than 12 volts with full load. Go to any store that sells battery's for them to test. Your battery is usually not under a warranty, but if it fails this test maybe you can complain and get one, or just shell out bucks somewhere else to buy one. Autozone will test and install free of labor charge right in the parking lot. Weak battery is a huge cause of intermittent electrical problems in grand cherokee, dealers never admit it and always look elsewhere for some reason.

May 02, 2010 (5:00 am)
The last few months, sometimes my 97 JGC won't started after I turned the key, there is no power and I checked the battery terminal, it was good, the inside light was not on when the door was opened, but I can see the light under the hood was on, and hear some squeeky noise under the glove compartment, sounds like the relay/coil... or something trying to start or kick on... and sometime I slam the door few times I was able to start the car... It was just frustrating because it was intermitten, but the last few days it happended so often... Any suggetstions???

1) Check to make sure that your battery terminals are clean and free of corrosion.
2) Ensure that the battery connections are secure to the battery. Even though the hood light may be on, it may be dimly lit. Jiggle the battery connetions around to ensure that they are TIGHT!! to the terminals; you'll know that you have a good connection when the hood light is brightest.
3) The BCM is located under the glove compartment. A common issue with the older JCG's is that the BCM contacts become corroded and cause all sorts of electrical problems. One solution is to:
1) Disconnect the battery
2) Find the BCM; Pull the module from it's plug.
3) Clean the contacts thoroughly with contact cleaner. Wipe the contacts dry.
4) Reconnect the BCM and battery.
#292 of 735 97 jeep grand cherokee transmission sensor problems.
May 05, 2010 (3:51 am)
I have a 97 Grand cherokee. Engine light on. Replaced fuel pump, wires , rotor , cap , plugs, o2 sensor, trans sensor ( on 3rd one in one week). Was running fine after, trans sensor, engine light still on, after 02 sensor was installed trans sluggish, feels like emergency brake on. Three mechanics, no solution. Also, have a friend had same problem. No mechanic could solve it. Tranny eventually went and scrapped it. There's an answer for everything in this universe. What's this one? (tranny was running fine before 02 sensor, although idling a little rough, sometimes hard to start) The last mechanic said he's not getting a reading from something and he can't get a diagnosis on the scannerómentioned possible govenor problem in trans. Anyone got the inside skinny on this problem, sounds like it's not only me??

I just ran into this problem, and for my situation, it was the the rear hatch. there was a short (Open) in the housing for the rear latch assy. IF it's no bother to you to have ALL your electronics working, you can disconnect the harness, and be on your way, but in my situation, I had the rear hatch assymb. replaced and of course it's a dealer part, so they soaked me $200 just for the part, and it took only 30 min. to install. You might be able to find a perfectly good replacement at a jeep graveyard.

Has anyone or can anyone help me out. My moon/sun roof has a random glitch. On occasion when I go to close the slider, it will connect with the "Saftey" bar and re open half way. when that happens I have to push to close several times before it actually completely closes. any ideas?

May 05, 2010 (4:30 pm)
I have changed the battery but there is still a strange ticking sound underneath the driver's side dash. The windows or AC will not work. Radio does work. It did this about 2 months ago when I started it....the lights went crazy blinking on and off, etc. We unplugged the battery for the night and that worked. However, it did not work this time w/the new battery. Any suggestions?

Just to update... I think the problem with my Jeep might actually be solved. The dealership took apart the entire dashboard and went over every connection. In doing so, they found "MULTIPLE" ground wires that were loose. They fixed them and I have had no problems since that correction has been made.
