I replaced the battery of my 96 Grand Caravan. Now when I start the vehicle the push button switches that control the air conditioner, and the air recirculation "blink" off and on. This is the yellow light in each button that signals when the button is depressed. Sometimes while driving for a long period of time they stop blinking, but come back on when the vehicle is turned off and restarted. They blink at the same time. Apparently there is a way to re-set this by pushing a combination of buttons? Help.

 

You need to clibarte the climat controls
turn the car on
put the ac on full blast
the controls are in a lL shape
press the top and bottoms buttons at the same time the system will start the cool down process
after this cycle is done you will need to press the far left and the far right button at the same time this will start a air blend door calibration just ket it run for a few minutes if this is done right then only one button will be left on at that point you turn the car off then turn it back on and it will be ok.
