2011 Wranger Unlimited Heater Issues

I've read through lots of threads here on other heating issues but they all seem to be about No heat at all, or heat only working on one side or the other.

My issue is that the heat starts blowing fine. Good and warm from all vents but after about 30 minutes it cools down and starts blowing cold air.

The temperature dial is supposed to maintain a temperature. I've got a Canadian model so the dial goes from 15c-30c. And I like to set it at 22c. My first thought was that the thermostat was blowing nice and warm until it reached 22 ambient temperature then would throttle back the heat to maintain it and Im just reacting to the difference in air skin contact.

But I stuck a thermometer on top of the dash and it never gets about 18c. Ever!

Turning up the thermostat doesn't make it blow warm once its cool either. The only solution is to crank it past the 30c to the Red dot but then it blows air so hot it's stifling. 15c-30c cold and frigid, Red Dot blast furnace.

Any one else having this problem?

From your description... the problem could be a bad or dirty climate control temperature sensor.
Have you had any problems maintaining the temperature when using the climate controls with the air conditioning?

I'm having this same issue. How does one clean a dirty climate control temperature sensor?

The sensor is usually located behind the panel beneath the steering wheel to the right. You should see a few small louvers identifying its location. If its dirty with dust; you can blow it off with compressed air. If this doesn't work... the sensor may have gone bad at a certain temperature range; which will require a replacing by you or the dealership.
