I drive a 2007 dodge nitro and noticed that the driver side heat is not as hot as it used to be and is cooler than the passenger side heat.

I do not have dual heating controls. I notice that as you go from left to right from vent to vent it gets warmer.

Any ideas on a fix and if I would be able to trouble shoot / fix with minimal automotive knowledge.

If not, ideas on a cost estimate for repair?

Thanks!

    That’s a heater core getting clogged. I did one last month on a Jeep Liberty (cousin of the Nitro). It cost about $200 in parts and 7.5hr labor.

      Thanks for the help! Looked into this some and after I got home last night I found a video on how to diagnose this by checking the inlet and outlet temps. I let the car sit for about 5 minutes while I got the temp gun and watched the video, started the car and ran the heat full go for a little bit. The inlet was ~175° and the outlet was ~150-155°.

      From my understanding the difference is not too large, but the temps might both be low? Curious what you thought.
