Folks-

A few years ago, I had to switch out the battery in our 1998 Dodge Caravan.
After doing that, for some reason, the little yellow lights by the A/C
button, air recirculation button, rear windshield wiper button and rear
window defrost button. These things are still blinking. Anyone have any
idea what's going on, and how to correct this?

Thanks!

Get the vehicle to operating temp, fan on high and the temp controls to the
far heat position.
Press and hold the rear wiper and washer buttons at the same time
until all L.E.D's light, this will put the heater control head unit in
calibration mode, when done 2 L.E.D's (rear wiper and washer) will
flash
alternately and then stop when complete.

How long does that re-calibration take? What does it mean when the AC button
and recirculation button keep flashing, with the rear wiper button flashing
once every 3-4 cycles?


Thanks for the assistance. It's greatly appreciated.

It means it lost its calibration, just do it! it takes 2 minutes
