Pathfinder 2014 - Rear Heating

Recommended Posts


I own a 2014 Nissan Pathfinder SL. I noticed that when the rear heat is on, it takes around 30 minutes for the rear to blow out heat, even though the front has already been blowing out heat. Also there is not enough air force for the heat. Outside temperature is about -5'C.

What could be the issue?

There aren't a whole lot of R52s on here, and I haven't heard of this particular issue. Best I can do is link you to the service manuals.


The auto climate control in my '93 doesn't kick the fan on full until it sees the coolant temp has come up, so it's not blasting you with cold air. Might be the coolant temp to the rear heater core (assuming it's got a separate one like some minivans?) is taking longer to come up in the cold, and the fan isn't kicking in until the heat reaches the core. If the lines run underneath, might be worth checking that whatever insulation they've got is intact.
