My chevy lumina has suddenly started doing a strange thing it takes forever for the heater to get warm all the while the temp guage is risingto a little over 1/2 way but that is more than usual. then the temp guage goes down very rapidly and the heat gets warm. the at a stop light or when idling the same thing again and again what could this be?
