Cruise control no longer works but the dash light comes on, in addition on the same day the heater no longer blows at the floor or through the dash vents, only at the windshield.

What switch needs to be replaced? No cruise and blower only blows on windshield. What switch needs to be replaced? No cruise and blower only blows on windshield.

check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.
The tachometer is the problem it's jumping causing the cruise control to not engage. Jeep can fix this problem in a day for you at a small fee of course. Unless you're a mechanic don't try this one alone.
check the vacuum line on the right side of the engine. There should be an elbow connector connecting the line to the engine. Does interior fan only come out of the defroster vents by chance?
Check fuses/relays and make sure they are all good; if so check the electrical wiring/connectors in the dash. Jeeps are notorious for loose wires in the dash.
Faulty product. I install cruise control for 6 years. One of the cables are hooked into the throttle and the other in the vaccuum actuator, since it is electronically controlled actuator, the object itself might be losing it's contents or frankly worded, is taking a nose dive. works much like a brake booster does.
Is it a PID system? (Proportional integral derivative system)
or is it just standard proportional?
That will play a factor.
If you just have one of those cheesy controls (cruise controls), than replace it, obviously it wouldnt of cost much. if it is not, check the actuator and replace it! Replace the Fuse, brush it with wire brush, clean up all connections.
You should be ready to roll!
On my 05 Wrangler Unlt'd Ruby - The vacuum hose on the drivers side of engine had come off, which disengaged my Cruise and the actuator which determines whether my heater points to the vent, Defrost or feet. Put it back on and secure with a cable tie.
If it is like mine, you will then have idling problems, especially when coming to a stop. You will need to clean the throttle body because the engine has picked up **** through the open port while it was off. Directions for that exist on this site elsewhere.
All of these are easy - i hadn't worked on a car in >25 years and it took me 30 min.
