It was pretty bad when on our way our van started to smoke from the dash, the heater control board burned out and started to smoke. In order to keep it from catching fire we had to turn our heat off and keep it off to get the van home. It was took apart and the board that runs all the heat, a/c, stereo was burned. Very scary when smokes comes from the van and your not sure what's going to happen next. Something for all of you Caravan owners to keep in mind.
