Rear heater problems

Heater problem V8 All Wheel Drive Automatic 110000 miles

My rear heat and air seems to work just fine but the front doesn't work correctly all of a sudden. In the front I can feel just a small amount of cold air or heat but not the full force like usual. It seems like a blockage or something. I can hear and feel a change with the venting as I change from floor to defrost but hardly any air comes out. Also I hear the blower motor run faster and slower as I change the speeds.
Do you have an idea as to a solution?

Thanks Gary

Hello

It sounds like you have a rear air temperature blend door actuator that is out not changing the cold to hot. Here is a guide that will show you what you are in for when changing the actuator out.

Here is the location for your car (below) REAR

I have also included the front ones as well because they go out from time to time I thought it would be good to have.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Jack

Thanks! I got the shield off now there are some wire clamp screws but not a set screw that I see anywhere. I cannot find the mentioned set screw and how does the cover remove after I take out the set screw?

Try removing those screws. After removed, the cover should pull down out of the way. See pic
