Sounds to me as if a couple of fuses have blown. There must be a reason why they blew, sometimes is wires grounding or broken wires somewhere under the panel. Better taking it to a professional as could be something simple or something rather complicated. Good luck

This is a very common problem with many of the mid 2000 truck and SUV overhead consoles. The console is very prone to internal failure. I offer a reasonable repair service with a lifetime guarantee, check it out: www.autoclockrepair.com
There is a bunch of useful info there. Drop me an email if you have questions, thanks!

Ok, the '03 Jeep Grand Cherokee uses a small vacuum line to control the servos. Since your light comes on, it's obviously getting power. 9 out of 10 times it's the vacuum hose.
Pop the hood and look on the passenger side towards the back for the engine coolant reservoir. It's most likely underneath it so you may have to remove the res. Check the vacuum hose and all vac. connections then check the electrical connections. If that's not the problem, check the cruise control connection to the throttle linkage.
If that still doesn't do it, you may need use scan tools and diagnostic procedures that are out of the scope of home mechanics.
Wish ya luck!
