#3812 of 5143 94 JGC Doesn't Go Into Overdrive
Nov 17, 2007 (6:52 pm)
I've owned my '94 Jeep Grand Cherokee Ltd V8 automatic trans. since 1995. It's been pretty decent with the normal repairs,140,000 miles. Last month the battery was dead, charged it up, the next day it was dead again. Had it towed to a shop near where I live. I had a remote starter for years, they told me it was bad and was draining the battery and disconnected it. Next day dead again, they told me it was the security system and were going to disconnect that. Next day, dead again. Then they said it had "electrical problems" and finally replaced battery and negative cable tip, which solved the problem. $220 for labor, $105 for parts, and no remote starter anymore. Two weeks later, I had a security lock out; come to find out, the security system cannot be disabled. Took it to the Jeep dealer, in their words, they had to "trick system to get veh running then unhook theft system and let run so PCM would not recognize theft system. If battery is disconnected or replaced, it will need to have steps repeated to activate and deactivate theft system." Another $305. Everything's fine, no theft system, but now Jeep won't go into overdrive. It's not the OD button, checked that. Took it back to Jeep, now it's a bad computer and will cost $800 to replace. Being a woman who knows next to nothing about vehicles, I don't know what to think. Any ideas? Thanks!

Sounds to me like they DID NOT take the neccesary prcautions when changing the battery the first time. Some vehicles REQUIRE some kind of battery back-up when changing the battery, Most times it is some kind of battey or deivce that plugs into the cigarette lighter and all it does is keep the system with another power so it doesnt loose memory / programming (main computer) .
I think the shop is responsible for the problems becuase of the MIS-DIAGNOSIS the first time. Possible they cut a wire for the remote started that caused some kind of system error. There are many different things that could of lead up to where you are but what I do know is that iof they would of used a back up battery device, changed YOUR battery and terminals and then removed the back up device, you would not of had any problems with the theft system or other issue. (IN MY OPINION)

I too was havin small things go wrong with my 98 jgc simple little things that didn't make sense...before you get a new computer for $800.00 go to a junkyard and ask for a used one out of a wrecked jeep,I just happened to have a friend that knew someone that had a computer i put it in mine no more problems you could tell a difference when you first cranked it up after i put it on,but anyway i got mine for $75.00 there is also a place on here on ebay look up computers for the make and model and it will come up with a place in florida that sells them for $400.00 which to me is a lot better than $800.00 i got lucky with mine....i don't take it to the dealership anymore they are a ripoff.......but they have to get your vin number to put it in the computer they send you to make it work.........hope you get it fixed.....Good Luck

Thank you for the information. I didn't know any of that. I too believe they're responsible, and since I paid with a credit card, my bank has filed a complaint for me to try and get some of the money back. So we'll see what happens.

#3818 of 5143 Fuse Location on '00 Grand Cherokee
Nov 22, 2007 (8:42 pm)
I was looking for a fuse in my manual. when looking and trying to identify some of the fuses from the owners manual with the fuse box, i saw a few that i can't find. It would appear that you can't get to them without pulling the steering wheel cover off. Does anybody know about this? Are these accessible?

hi, just bought a 98 grand jeep, when you put your foot down it is spewing clouds of black smoke out. thought there was a problem with air flow sensor , car didnt smoke when this was diconnected, ran slightly better as well. after spending 90 quid on a new sensor , i have reconnected and it still spews smoke out when you put your footdown. as soon as you disconnect the lead to the sensor the car runs with not a sign of any smoke although it does run underpowered. any suggestions would be appreciated.

#3821 of 5143 2005 axle mounts JGC 5.7L
Nov 27, 2007 (11:22 pm)
Has anyone had to replace the axle mounts located on the front differental case? There are two: one on the upper left and one one the upper rear of the case. They are 37.00 dollar parts but the labor is well over 500 bucks. IF THEY ARE TORN ON YOUR JGC THE ENGINE WILL SHIFT VERY HARD FROM PARK TO REVERSE OR FROM PARK TO DRIVE. BUT NOT THROUGH THE GEARS. I feel this is a problem that Jeep needs to address as a recall since more and more JGC are having this problem....and the parts are on backorder.
Let me know
