Having similar problem. Anyway to check temp sensor in cabin? Anyway to bleed potential air lock from heater core?

 

There is a plastic bleeder screw on the heater hose right before it goes through the firewall into the car. That might help fix your problem.

 

Thank you for your response. TrevorM

 

What vehicle do you drive? What year?
in my LR2 there are independent temp settings for passenger and driver. Therefore independent sensors as well.
I would suspect if it was a sensor, you would throw a error/trouble code.
