98 Grand Caravan blinking lights

[mikejames1114]

Has anyone else experienced blinking lights on the front console (rear wiper, defrost, a/c and air circulation buttons)? It seems to blink everytime the van is started for awhile then it stops and the lights go off. Everything still works when you push the button, even while it's blinking. Any ideas??? Thanks in advance.

You need to recalibrate the ventilation system. Here's how: Start the van and turn on the blower. Simultaneously push the top and bottom wiper buttons on the left side of the ventilation control panel for 5 seconds. All the lights on the panel will light up. Then two lights on the left side will alternately flash for about two minutes and you'll hear the ventilation modes cycle. When just the top light on the left side slowly flashes push that button and you're done. All lights should be out and you should be back to normal. Restart the van a few times and make sure. This is the ventilation control calibration test and it resets the ventilation system computer.
