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.

 

I think there is something wrong with the climate control my 94 dodge interpid did it but on the rear defrost light it was a problem code. Try holding down on the switch that flashes for 5 seconds it should flash a code. I would go a buy a repair manual it should help and since it is only around $20 it will help you on other problems.

 

All you need to do is start your the vehicle. (if you are unsure what **** or lever is which I am looking in the manual for proper terms) Then slide your temp lever all the way to the right (full cold). Then turn the Mode Control to 'panel' (the one that sends air to your face only). Then turn the 'blower switch' to all the way to full. Now go to the leftmost three buttons. Press the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid). Hold these two for a few seconds. Once the lights come on solid then begin to flash you can let go. The AC will now calibrate. You will feel the air blow out of all the different zones at different intervals and see lights come on and go off. Then after a minute or two the top bottn you pressed will be slowly flashing. This means it has been completed (I actually let it run for 5 more minutes just in case something else started blinking). Press the last flashing button and you are done.
