Put new brakes on and that didn't solve the problem (although it did need new brakes). Manual says if both the above lights are on there is something majorly wrong with it and should take it to get serviced.

I have a 2006 grand cherokee laredo 4x4. I have only had it in four wheel drive once, and thats when i bought it. Yesterday I was just testing it out. Put it in neutral,foot on brake, Pulled up on the the leaver and nothing happened, except a service light came on. Saying"service transfer case". No matter what I tried I could not get it to work. What say you.
The 1999 Jeep Gran Cherokee has standard all-wheel antilock brakes. The new braking system has electronic brake distribution capability, which makes for a quieter, less pulsing and more balanced braking experience. Possessing the largest brake rotors in the sport-utility segment, the Grand Cherokee meets or exceeds requirements for passenger vehicles, which are stricter than those for light trucks. ----------------------------------------------------------------------------------------- Original Launch X431 Master
Hi Lorraine, I was reading through your question and noticed you description of what your brakes did when you were (i assume) driving in wet weather conditions.
Jeremy W. is absolutely correct on this one.
However, due to your comment I would like to add this:
What you most likely experienced was a NORMAL activation of the antilock brake system. When one or more of your wheels begin to slip on the pavement, your brake system will go into "antilock mode" This will cause the brake pedal to kick back at you a little and start vibrating rapidly. It feels really strange when this happens if you have never experienced it before.
I would suggest doing this to get to know your car better. The next time it rains, drive your car on a side road away from traffic and while doing 15 to 25 Mph, hit the brake really hard. The brakes should go into antilock mode and you will feel the sensation that you felt before. This way you can get used to it and won't be nervous to drive because it can build your confidence in your brake system and familiarize you with the normal operation when your wheels are slipping.
Some people drive the same car for YEARS and never had this happen because they had not been in a situation where the wheels began slipping. Then totally freak out the first time it DOES happen.
Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individuallyto prevent them from locking up. Antilock systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails topass thetest one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!
Just pull up on the 4 wheel drive lever .. You can shift on the fly to part time and full time but you gotta stop and in park or neutral you can shift into 4 wheel lo .. I have one myself .. love those jeeps .. you "understand"
An ABS system will have wheel sensors installed. Remove one of your wheels and look for a wiring harness that runs to your steering knuckle(the part that you brake rotor and strut is attached to. Also, either you front half shaft or brake rotor will have what looks like gear teeth on them. These are the magnets the sensor reads. If your Jeep has either of these it has an ABS system. Secondly the chassis on the Cherokees should be the same irregardless of trim level (limited vs regular). These trim levels affect the interior trim and power extras only not the mechanical parts.
