Thanks - more context. Jeep is new to me so don’t know if CC worked or not. Factory install, switches on sides of steering wheel bottom. They appear fine. Clock spring (old and new) had green wire connected to switch harness. Jeep is in great condition and all the parts look fine. Vacuum hose out reservoir looks/feels fine. Followed all the thin vacuum hoses and nothin readily apparent. Solinoid/actuator looks fine and is connected to throttle. Went thru all the fuses (engine compartment and behind glove box) and added some to the Assy slots that were previously empty (just in case). Reset PCM per correct process and now running like crap as it relearns so pretty sure I did it right. Brake lights are not on all the time so think switch is OK. All lights are LED but have appropriate relay to stop the fast flash it originally had. When I do the dash diagnostic (turn assy on, press odometer and hold, and then turn ignition switch between off and on 4? Times) the “cruise” light does come on so I know it is good. However, at no other time do I see the cruise light - not when I first start the Jeep (am I supposed to?) nor even a short flash when trying to turn cc on
AC and heat work fine through all three paths - defrost, central and floor
Engine is not rough and idle is consistent but if open to suggestions even if it’s to start replacing line or a ‘check valve “
