We just replaced the blower motor resistor in a 2005 santa fe and now the fan will only blow out the air if it is between the 2nd & 3rd position on the control ****. It seems to work fine if it is in this position but it does not blow air out otherwise. Any suggestions on what else this can be? The blower motor is working fine and we have already checked the fuses. Is there a diagram of what is under the dash so we could see where the different parts are located?
