Question about 2005 Jeep Wrangler

2005 Jeep Wrangler 4.0 Unlimited with automatic

A/C vacuum line recenlty "fell" off. Found out when the a/c and heat only blew from the defrost vent. When I replaced it, and upon coming to a stop sign or LA stop and go traffic the idle speed rises and falls, rises and falls, then idles normally. Went through the vacuum lines connected and all seem to be in real good shape. One thing is that there is a vacuum line that runs under the battery into a black plastic box..??? Could this be something that has gone bad? or what do you think? Please and thank you very much.

Lyle.

    I have the same problem but the air conditioner has stopped working at all. The Fan only blows hot air.

    Had same problem. Replaced the vacuum hose, and now Idle fluctuates when at a stop sign. When driving, RPM's stay high, even when foot is off the pedal. I have a manual transmission. Any Ideas?

The best fix is to clean out the throttle body with throttle/carb cleaner. Dry up the cleaner fluid and start the engine. You'll see a hole (inside the throttle body) that leads to the idle air control; shoot some of the cleaner in there. The engine may stall while doing this, but restart the engine and repeat a few times. After that, turn the key off and disconnect both battery terminals. With the battery terminals off, turn on your headlights. This will make the system look for power and reset your idle to normal. Reconnet the battery and check the results. Hope this helps.

2005 jeep wrangler blows warm air not cold


Well this is different since most questions now are about no heat.
If one ac line is cold and the other is warm, I would suspect a blend door under the dash is not working. The blend doors direct air thru the heater core and the vents.

2005 Jeep Wrangler Unlimited cruise control will not engage.


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?

Heater only blowing out defrost vents


Open your hood and find a "T" connector right near the battery. Follow the line down below the battery (you will have to get under the Jeep). You will see that the line plugs into a 3 to 4 inch section of 3/16" tubing that is plugged onto a black in color, plastic box. Use a razor knife and trim off about 1/2" of this 3/16" tubing as it commonly cracks where it fits on the nipple of the black plastic box. The vacuum cannot build pressure properly with these cracks in this tubing, and therefore cause the selector door to malfunction when operating heat and a/c. It is a quick and easy five minute fix.

Cruise control does not work on 2005 Rubicon. Light on dash work , but cruise control doesn't


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.
