#1147 of 5143 Jeep can't take the heat
Apr 27, 2005 (9:26 am)
My Jeep cherokee 1996 is not doing well in the heat. The water light comes on when its over 80 degrees out or I ran my air or drove for a while in the heat. I have had my thermostat and my radiator checked and they seem fine. As soon as this happens I run my heat and it cools a bit. I heard through the grape vine that some jeeps are made with a small fan that does not cool off the car and needs a special kit installed for this. Please help, it will be 90 degrees soon and need to fix it. Thanks

Just wanted to say that I found out the only thing wrong with my Jeep was it needed a new crank shaft sensor. I really learned alot in this forum and knew what to ask the mechanic to check for. So I didn't have to use mechanic 1, who wanted to replace the computer or mechanic 2, who was 100% that it would not start by simply replacing the crank shaft sensor. I found a good mechanic who thinks I might know what I am talking about by the questions I asked. Thanks much.

Excellent! I'm glad we were able to help on this.
Having a little information goes a long way when dealing with some mechanics.

I had a similar problem with my '95 GC. The positive battery cable connection had corroded (turned black) at the battery post. I replaced it with an aftermarket terminal. I still run my '95 and have had to replace the terminal periodically.

Hi Gallagher05, I also purchased a 2003 Jeep Liberty and it has been in the shop 7 times for rear brake noise, warped rotors, leaking axel, and a clunking noise when hitting the brakes backing up. I am experiencing what you went through. I have contacted a lawyer and starting the lemon law process. So far their response has been "no" since the problem is not life threatening so to speak. I am saddened because I really thought when I bought the Jeep Liberty that this would be the vehicle for the next ten years. I am scared what it will cost me once the warranty is up. I am considering filing a complaint as well with BBB and the State Attorney General. If we had a collective voice of Jeep Owners who have been treated this way, do you think it is possible to contact a radio or television venue like "7 on your side"?
#1153 of 5143 Re: JGC '97 Starting problem [emlee] No Start and Dancing Gauges
Apr 29, 2005 (2:28 pm)
I recently had similar problems with my 99 Laredo I 6 with occasional no start (nothing) but sometimes with flashing on and off ABS warning light and dancing gauges (even after the ignition was turned off). The connections and terminals seemed tight and clean so I took it to a mechanic (not from the dealership) who said there were no error messages about the brakes on the computer and that my 1 yr. battery was bad and unable to hold a charge. Then the battery dealership claimed the battery was fine but found a loose terminal connection. Apparently some one had over tightened the set screw for the battery connection and stripped it enough to have partial contact. Battery Guy then ground the terminal down slightly to allow the set screw to catch and have had no problems since (2 weeks now). So it appears that the charge to my Jeep was fine sometimes and allowed it to start or was compromised enough to confuse my sensors/computer or bad enough to keep it from even turning over because of a slightly loosened connection. Hope this helps.
BTW I just want to mention that this is our first Jeep and has over 87,000 miles and we love it. We live in Northern Indiana with lots of ice and snow in the winter and has also been great for long trips to Miami during the holidays.

I was amazed to find the exact thing happen to my 95 JGC Laredo. I have 155k on it and it never gave me a bit of problem. Yesterday morning I went to start it and I found it does not have any spark. I called a few local dealerships and they of course tell me to bring it in so they can hook it up the the computer for diagnosis. I am curious to see what they found your problem was found to be as mine is more then likely the same thing.
#1155 of 5143 95 GC Wacky Electrical Problems
Apr 30, 2005 (6:11 am)
I have a 95 GC Laredo with only 88,000 miles. Recently the Vehicle Information Center has started resetting itself (Like the Battery was disconnected), the power windows work intermittently and the security alarm system sets itself when the vehicle is turned off. I'm guessing that it is the PCM but am looking for other ideas before I spent $450 on one. Anyone out there with similar problems? Also, would a electronic diagnostic tester work for pinpointing this problem if it did have a bad PCM? Thanks

Apr 30, 2005 (12:58 pm)
It's likely that the heat from the rotor has rusted the rotor to the hub. There is no trick tool, just patience, a few careful raps from a well directed hammer and some WD - 40.Keep working on them, they'll come off.
As for warping rotors, like so many cars these days, the rotors warp due to the calipers freezing to the slide pins. There seems to not be enough clearance in the pin holes and that's probably due to the caliper being improperly annealed during manufacture.Annealing during manufacture is supposed to reduce or eliminate heat - induced distortion in use.
That is, as the caliper heats and cools during braking, stresses are introduced that distort the caliper just enough to keep it from following the rotor properly. The machined slide pin holes in the caliper cease to be straight as the heat stresses (distortions) build up. The rotor seizes to the slide pins causing the brake pads to stay in contact with the rotors, even after pedal presuure is released. The rotor stays hotter longer and over time the extra heat causes it to warp. If this does not seem plausible, ask an engine rebuilder if he has ever line bored the crank and cam journals on an engine block. Large pieces of machined cast iron CAN distort, if regularly heated(overheated) and cooled.
I found that the rotors on my Jeep warped very quickly as well. Getting one rotor off was difficult so I used a hammer and a few carefully placed raps to dislodge it. I replaced the rotor, of course.
Then on all four calipers I de burred the slide pin holes using a drill and a properly sized bit. I don't recall the size of the bit because I did the work 70,000 miles ago. That's right...the pads and rotors have lasted 70k miles! The right rotor has warped just a bit again but I will fix that soon when I do the next brake job. I was a bit more aggressive on re - machining the the left caliper slide pins holes and that's why that rotor hasn't warped.
When you re assemble, be generous with the anti seize compound on the slide pins. Re lube every 5 -10 k miles.
If you go for the real "fix" as recommended by Chrysler, replace the OEM calipers with the recommended Akebono calipers. The Akebono calipers don't seem to cause as much rotor warping. They are noted in a Techical Service Bulletin that every Jeep dealer should have in its records. This is not a recall item, even though it probably should be. At $125 per caliper plus installation, I took the re - machining route.
If your are a bit faint of heart or if your idea of heavy work on the vehicle is checking the oil, have a good garage replace the calipers for you.
