Our '96 Sport Caravan has only blower operation with the switch in high position. Auto Zone has the two resistor unit in stock, at $ 13.99. Question; Is it in engine compartment or in cabin? Could resistor failure be related to "thunking noise" ( 3, up to 13 thunks!) on startup? Does not do it when switch is left in high position. Sound comes from passenger footwell area under glove compartment TIA
