Cruise control not working

You will need to get it scanned and see where the problem is. Most of the "free scan" places will not scan for ABS codes. Most likely a wheel speed sensor but without the code to say if it is a sensor or wiring issue you could change every sensor and still have the light. It could even be an issue in the transmission itself. There have been other issues with them involving the steering control module and bad connections so getting the scan is the best first step.

The code(s) will point the way. But a code generally does not say "change this part", it simply tells you what the computer sees as a "bad input"
For instance, a bad wheel bearing could cause enough play that the speed sensor freaks out. The computer cannot talk to the bearing but the sensor signal changes and it says "sensor input is bad, turn on the ABS light" The sensor itself is not the issue it is the bad bearing.

You are welcome. Once you get it scanned come on back and we will see if we can help using that information.
If you decided to DIY it you can get a reasonable scan tool that would read the data you need for around $200.00. Something like the Innova 3100J or one of the Autel units that has ABS/SRS abilities (multiple units with various prices, just look at the manuals online to be sure it covers your vehicle though)
As a bonus you can help your friends and family with their vehicles.
