I have a 1984 500SEC that has a heater problem. The blower works fine and I think it is in the wheel of the push button thing but not sure. Ok heres the problem if anyone could help that would be great because I am tired of being cold. The tempature wheel can be set at cold and blow all day long but as soon as I advance the wheel to increase the heat, it will blow for a second or two and shut off. I can roll the wheel back to cold and it will blow the hot air out for a second then go back to cold. I seems like it is cutting off as soon as it gets warm. I have been able to hold the temp wheel and slowly increase the temp and every once in a great while it will stay on (blower). Is this a resistor or something? I thought about replacing the climate control pushbutton unit but being I would be just guessing I thought I should ask advise first. Thanks to all
