Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to Just Answers. This is a very common issue with the Rogue, and unfortunatley there is not real solution the manufacturer has provided. There are some options however. You should check and make sure there is no crimped of pinched heater lines going from the engine to the heater core. The hoses will be going directly into the fire wall. There will be a feed and a return line. Secondly the heater control valve opens when you turn the heat on inside the car. When the valve opens it sends hot coolant through the hoses, into the heater core and air is blown over it providing hot air inside the cabin. If the heater control valve is faulty the valve will not open. You can bypass or remove the valve if you are experiencing cold weather an know you wont need AC for a few months. The issue may also be related to the control module which tells the valve to open and close.
