No heat in the cabin.
Posted: Tue Oct 13, 2020 1:28 pm
I have an '08, LE, R51 Pathfinder with no heat in the cabin. I have verified the system is properly serviced with coolant and
know that the engine coolant is running at 195F. So I have looked into the heat control valve assembly that is mounted on
the passenger side firewall in the engine compartment. I have taken the valve and hose assembly out of the car and am
wanting to buy a replacement, the control voltages are getting to the valve, however, it is not opening. Occasionally on a
rough surface it might open and allow some hot coolant in the heater core, but 95% of the time it won't actuate. I am having
a tough time locating a source of supply that is not the dealer. I have studied many threads and youtube folks that show you
how to troubleshoot the valve and hose assembly. Does anyone have a good part number for a Pathfinder that might be out
there and considered an "Aftermarket" part? These items seem to be a high failure component, all I can find are the ones
made for the Titans and the 5.6L Armada series vehicles. Any assistance is appreciated, I just hate to go to the dealer and buy
parts. Thank you.
