If the A/C and heat both work, then this is most likely just an issue with the mode door.

Here is a guide that will help with talking about this:

While there could be a couple things causing this, I am pretty confident to think that this is the actuator. So, let's change that out and I am attaching the instructions below on how to do this.

Please let me know what questions you have with this.

Thanks
