Jeep Wrangler: Manual Climate Control Descriptions And Functions / Recirculation Button

Push the recirculation button on the faceplate to change the system between recirculation mode and outside air mode. The Recirculation indicator and the A/C indicator (if equipped) illuminate when the Recirculation button is pressed. Recirculation can be used when outside conditions such as smoke, odors, dust, or high humidity are present. Recirculation can be used in all modes except for Defrost. Recirculation may be unavailable if conditions exist that could create fogging on the inside of the windshield. The A/C can be deselected manually without disturbing the mode control selection. Continuous use of the Recirculation mode may make the inside air stuffy and window fogging may occur. Extended use of this mode is not recommended.

On systems with Manual Climate Controls (if equipped), the Recirculation mode is not allowed in Defrost mode to improve window clearing operation. Recirculation is disabled automatically if this mode is selected. Attempting to use Recirculation while in this mode causes the LED in the control button to blink and then turns off.
