have a 2001 pathfinder, heater won’t blow heat, what could be the problem, heater core?


It could be a bunch of things but I had the same thing happen to me with my van last week. It stopped blowing hot air even when it was warmed up. Turned out it was leaking water. I was almost totally out of water/antifreeze. I had the leak repaired and fill back up with antifreeze. My heat works perfectly again. Just thought I would share since it could be something as simple as this. Good luck!

    first thing to do is to check and see if your thermostat is opening. you can remove it and put it in some water and boil it to see what temp that it opens. a heater core will most likely leak fluid on the passenger side floor.

    It most likely isn’t the heater core, it’s probably the thermostat, water pump or blend door. WHens the last time you had the anti-freeze flushed
