Hi, can anyone help please have a 2006 Chrysler grand voyager diesel. Just bought it but the heater blower doesnt work; The car lets in warm air when on the move. I have replaced the resister to no avail. I pushed the power and recirculation buttons and that throws up a flashing delay signal continuously. I hear something somewhere trying to start so maybe the heater motor is faulty? Anybody got any ideas? Thanks Ian
