Hey I have a 2004 JGCL and while I am driving my speedometer and RPM will go crazy then all my gauges will go down and then I will die. Sometimes it will restart sometimes it won't. They have replaced the ECM, the auto shut off relay and now they are saying it could be the wiring harnes which will run me 2,000 dollars. Also my A/C Clutch fuse keeps blowing. They say the clutch is bad. ANY IDEAS???

Replying to: daveriggs981 (Sep 30, 2008 10:50 am) After replacing your ECM, your problem could be wiring between BCM and ECM, the BCM itself, or both. Or it could be a wiring harness for ECM that connects to engine. Because dash is acting funny, I would look at BCM first. The only way to know what is going on is to pull the BCM, inspect it and inspect wiring harnesses, i.e. the connectors that plug into BCM. I'd be very surprised to find a damaged section of wire 1/2 way between ECM and BCM. My BCM has 3 connects. 2 are 32 pin and one is 24 pin. The BCM has a lot of wires. It's a pain to get at. It's under dash. Mine is to left of steering wheel. Disconnect (-) on battery first. Start pulling panels off dash and you should be able to find it. You have to disconnect cables before removing it. Be very careful with connectors. It's easy to break the retaining tabs (I did it). Initially, cables are hard to disconnect. There is risk. The good news is that once you have it you can stop guessing all the time. 1. You could have a broken or bent pin where the cables attach to BCM. Replace BCM. 2. A single wire or group of wires may have pulled out from the connector. You only need repair these wires. Not replace whole harness. 3. The end of the wire may have gotten pushed back into the connector, but it didn't pull completely out. Inspect connector sockets with flashlight. 4. You can try re-installing the BCM and make sure connectors are on tight (push em in). Your problem may have been loose connector. If you have to really stretch a harness so it can connect to the BCM, that's probably your problem. The original harness is too short. You will have to replace harness. If you suspect BCM, you can probably get used one for about $200. It has to be programmed with info from your BCM or car won't start. I believe you can find this service on the web. Cost is ?, but certainly a lot less than $2,000. This is time consuming which is why dealer cost is high. You have to like your car or enjoy this activity. You will certainly know more about the problem. You could get lucky and spot something obvious that fixes it completely. Good luck |

I have just bought a 2004 grand cherokee Laredo Special Edition with only 5580 miles on it...that's right.....ACTUAL miles!!. My question to the experts is......Would it be a good idea to use Mobil 1 synthetic oil? I want to convert to synthetic oil, as i have on all my other vehicles, but would like to hear your opinions.

I have about 10 grand in repairs and upgrades on my 99 GC laredo V8 4x4 quadradrive 2. Dealer mechanic claims that replacing the 2 front tires only will destroy the transfer case, even though the rears are only 1 year old. I bought goodyear wrangler SSR all season radials for the front,(same as factory uses) and left the rears alone, since the fronts were bald. The rears have almost 90% of their tread left. BTW, I bought this beautiful gunmetal V8, heated leather clad seats, infinity stereo, etc. For 6500 in March 08. For a laredo, it has every option except cd changer. THANK GOD I BOUGHT THE CHRYSLER POWERTRAIN WARRANTY!!!!!!. Chrysler paid out 7200 in replacing the all wheel drive system, engine computer, trans computer, body computer, transfer case, all 4x4 related seals, battery, and two tires, A rental car was provided free. Safford dodge/jeep in Springfield VA is very honest and has always kept their promises, but I just dont buy the fact that I need to replace all 4 tires at once. Please help!! I dont want to mess up my finally-fixed jeep. Thx, Chris  Is the mechanic being truthful? The rear tires AREE the exact same size, but a different brand with a more sporty/passenger tire look. I need to go to buffalo in December...will transfer case go bad due to 1/4 inch tread difference?

Replying to: cskalski (Oct 03, 2008 11:36 am) when you replace only one axel the trans fer case will think that you are sliping one axel and then shift power to the axel with old tires then shift back and forth as you go down road with 1/4 inch deffrence the tire will travel aprox 1/2 foot less than the axel with new tires thus working the viscus clutch pack in the transfer (that is the weakes iten in transfer case) |
