The blower for the heater will not turn on until after engine temp warms up. And it can take some time after the engine temp is up, depending on how cold it is outside. The colder it is outside, the longer it takes for the blower to turn.

My Murano blows warm air only when the temp is set at the very top, otherwise it blows cold air.

this is auto temp control so have it scanned as it can be a any sensor or actuator causing the problem.

Hi
Code if 25 is for Sun sensor don't see that causing heater problem. System is quite complex and will need the BCM scaned to find fault. Is warranty out?
