Ram 1500/2500/3500: Manual Climate Controls Without Touchscreen - If Equipped

The controls for the manual heating and air conditioning system in this vehicle consist of a series of outer rotary dials and inner push knobs. These comfort controls can be set to obtain desired interior conditions.

Climate Controls

  1. Front Blower
  2. Temperature Control
  3. MODE Control
  5. MAX A/C
  6. Air Conditioning (A/C)
  7. DEFROST Mode

Front Blower Control

There are four blower speeds. Use this control to regulate the amount of air forced through the system in any mode you select. The blower speed increases as you move the control clockwise from the OFF position.

NOTE: For vehicles equipped with Remote Start, the climate controls will not function during Remote Start operation if the blower control is left in the OFF position.

Temperature Control

Use this control to regulate the temperature of the air inside the passenger compartment. Rotating the knob counterclockwise, from top center into the blue area of the scale, indicates cooler temperatures. Rotating the knob clockwise, into the red area, indicates warmer temperatures.

Air Conditioning Operation

Push the A/C button to engage the Air Conditioning (A/C). A LED will illuminate when the A/C system is engaged.


For maximum cooling, when MAX A/C is selected the A/C is turned on automatically and the air is recirculated.

NOTE: A/C cannot be deselected when in MAX A/C position. The LED will blink three times if the A/C button is pushed. If your air conditioning performance seems lower than expected, check the front of the A/C condenser (located in front of the radiator), for an accumulation of dirt or insects. Clean with a gentle water spray from behind the radiator and through the condenser.

Fabric front fascia protectors may reduce airflow to the condenser, reducing air conditioning performance.

Mode Control (Air Direction)

Mode control allows you to choose from several patterns of air distribution.

You can select either a primary mode, as identified by the symbols, or a blend of two of these modes. The closer the control is to a particular mode, the more air distribution you receive from that mode.

Panel Mode

Air is directed through the outlets in the instrument panel. These outlets can be adjusted to direct airflow.

Bi-Level Mode

Air is directed through the panel and floor outlets.

NOTE: There is a difference in temperature (in any conditions other than full cold or full hot), between the upper and lower outlets for added comfort. The warmer air goes to the floor outlets. This feature gives improved comfort during sunny but cool conditions.

Floor Mode

Air is directed through the floor outlets with a small amount through the defrost and side window demist outlets.

Mix Mode

Air is directed through the floor, defrost and side window demist outlets. This setting works best in cold or snowy conditions that require extra heat at the windshield. This setting is good for maintaining comfort, while reducing moisture on the windshield.

Defrost Mode

Air is directed through the windshield and side window demist outlets. Use the DEFROST mode with maximum blower and warm temperature settings for best windshield and side window defrosting.

NOTE: The air conditioning compressor operates in MIX and DEFROST, or a blend of these modes even if the A/C button is not pressed. This dehumidifies the air to help dry the windshield. To improve fuel economy, use these modes only when necessary.

Recirculation Control

Press the Recirculation Control button to choose between outside air intake or recirculation of the air inside the vehicle. A LED will illuminate when you are in Recirculation mode. Only use the Recirculation mode to temporarily block out any outside odors, smoke, or dust, and to cool the interior rapidly upon initial start-up in very hot or humid weather.


  • If the RECIRCULATION button is pressed when the system is in Defrost mode, the Recirculation LED indicator will flash three times and then turn off to indicate Recirculation mode is not allowed.
  • 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.

  • In cold or damp weather, the use of the Recirculation mode will cause windows to fog on the inside because of moisture buildup inside the vehicle. For maximum defogging, select the outside air position.
  • The A/C can be deselected manually without disturbing the mode control selection by pressing the A/C button.

Air Outlets

The airflow from each of the instrument panel outlets can be adjusted for direction, and turned on or off to control airflow.

NOTE: For maximum airflow to the rear, the center instrument panel outlets can be directed toward the rear seat passengers.

Economy Mode

If ECONOMY mode is desired, press the A/C button to turn off the LED indicator and the A/C compressor.

Rotate the temperature control knob to the desired temperature.

Also, make sure to select only Panel, Bi-Level or Floor modes.

Stop/Start System - If Equipped

While in an Autostop, the Climate Controls system may automatically adjust airflow to maintain cabin comfort.

Customer settings will be maintained upon return to an engine running condition.
