I own a 2002 Town & Country Limited. It has the 3 zone climate control system and recently the climate control (blower motor) runs continuously. When you switch off the climate control, the blower motor switches into recirculating mode (really tough when it is 20 degrees outside). If you turn the unit on, blower controls work fine (ie I can increase/decrease fan speed), but this is still hard to handle when it if very cold. All other controls seem to work fine except when I shut the unit off. Then it runs continusously.
I replaced the climate control with a used unit and it works exactly the same. I think it is not the climate control. Is there a sensor, relay or vacuum switch I should be looking for?
Any advice would be appreciated.
