My A/C works great, the heat on the other hand works every now and then and when the temperature drops below 40 degrees it does not work at all. What should I do? And one more the blower works just fine on all adjustments.

Hello, I'm Danny.

It sounds like you're having a problem with the blend door actuator. It's a small electric motor that opens/closes door that lets air flow through specific air ducts. Here is a tutorial showing what's involved in its replacement:

Below I've attached a picture of its location.It's under the middle of the dash on right side.I circled in red its location (A29). Hope this helps and thanks for using 2CarPros.
