1998 Crand Caravan Left key on, battery went dead, recharged battery. Everything works except the indicator lights on the 2 AC switchs and 2 rear wiper switch blink all together.
The procedure for re-setting the HVAC control panel on a 1998 Dodge Grand Caravan follows:
With ignition on but not running
1. turn knob to air vents
2. turn fan knob to ON
3. temperature setting on COLD (2X) {I have dual temp controls}
4.
hold top(rear wiper) and bottom (rear wiper with wash) buttons pressing
down together until all the buttons cycle through (this will require 1
to 2 minutes of continuous pressing)
I learned this from a very helpful local Dodge service adviser
The owners manual page 146 has the answer to the blinking ac lights
