How to Reset an Air Conditioner on a Dodge Caravan

by Diana Braun

The Dodge Caravan is a minivan manufactured and sold by the Dodge division of the Chrysler Group. The minivan was first manufactured in 1983 and remains in production as of 2011. The vehicle has an air conditioning system (AC) to cool passengers during warm weather and hot drives. The buttons of the air conditioning unit may start flashing due to a momentary electrical failure, in which case a reset of the AC is necessary. The procedure, commonly called calibration, initiates the self diagnostic test and system reset for the vehicle's air conditioning.

Step 1

Start the Dodge Caravan. Insert the key into the ignition and turn to the "On" position.

Step 2

Turn the Mode Control dial to "Panel." This setting only directs air to your face and upper body and not your feet.

Step 3

Locate the three leftmost buttons in the AC controls. Press and hold the top one and bottom one. The top button controls the rear wiper on constant and the bottom button controls the rear wiper washer fluid. The AC light should illuminate and then flash. Release the buttons once you see the light flash. The AC will start to calibrate and reset. Air should blow out of the vents at different intervals during the reset. The top button will flash when the reset is completed.

Step 4

Press the top button to complete the reset.
