Heater not blowing out of floor vents?

This must be a bad air temperature blend door actuator, or the control module is bad. Most of the time it will be the actuator, here is the location so you can swap it out which should fix the problem. You can try resetting the system which sometimes works as well.

You might want to try a CAN scan which may have codes that will help us. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Will do, thanks sir. I have a new GM blend door actuator on the way, I’ll let you know what happens when it arrives. Thank you. I sent a little donation to help along the way.

Thank you very much for the consideration ;) That should fix it, let me know how to goes.
