Low heat output

[CarlosHRNYC]

Sorry if I can't give much detail here. '04 Explorer XLS... I've noticed that when I turn on the heat, it doesn't blow hot air like my other cars do. Luke to moderately warm at best.

Anyone have any idea where I should start with troubleshooting?

It's tolerable now but once winter kicks in high gear I'm sure it will be a problem.

Thanks

You may be having an issue with the blend door which controls the airflow. Here is the results from a search I made:
