1995 Granch Cherokee Cruise Control

Have you checked your brake switch? These do go bad and if shorted will not allow cruise control to be engaged.

No I have not checked the brake switch, where exactly is the brake switch located and how would I go about checking it?

So even if my brake lights work could it still be the brake switch?

Yep. See below from Web. Google is a wonderful thing...

You’re not really going to find a fuse for the cruise control on your Jeep. Why? The cruise control unit is controlled by the vehicle computer and receives its power supply from the same computer. If power is not being supplied to the speed control servo you want to inspect the stop light switch. The stop light switch, on your vehicle is really 3 switches in one. One part of the switch is for the stoplights. The other two parts are for the cruise control and, if not operating correctly, the cruise control will not operate. Also be sure to check the vacuum supply to the cruise control unit. It is not uncommon for a vehicle of that age to have cracked vacuum hoses. A cracked vacuum hose will result in a loss of vacuum supply. Too little, or no vacuum supply equals no cruise control. There are a few checks you can make with a voltmeter, but to get down and dirty with the cruise control on your vehicle requires a computer scan tool too.
