Need Input. 99 Cherokee cruise control not working. Vacuum at servo 10 hg. no leaks. Clock spring verified through control buttons using ohms readings. Brake light switch replaced and adjusted. (old one worked too through continuity check) I believe the system does not work off fuse for control of speed just pcm ohms readings. The servo must work with 12v through pcm. Is there a fuse I am missing? My last thoughts are how to troubleshoot Servo assembly and PCM. Also no cruise light initiates at keyed accessory position. Any Ideas. Thank You.
