Just changed out the actuators for the front and I thought for the back too but now I have perfect heat in the front and no heat in the back at all is there another actuator in the back or is it a different problem and where is it located

You are correct that there is a separate system in the rear. More than likely there is a blend door issue in the rear but it could be low on coolant as well. Here are a couple guides that will help with this:

Also, I attached below the process on how to replace the rear blend door and to recalibrate it.

Let's run through this material and let us know if you have questions. Thanks
