Can you tell me if this actuator fits on my car and if it goes under my glove compartment. I tried to locate the actuator in the glove compartment and was unable to find it

What is the issue you have? The blend door actuator is 5 in the image, it controls temperature, it is the top actuator above the drivers footwell. Number 6 (below 5) on the image is the mode actuator it controls where the air comes out, floor, dash or defrost. The one on the top right is the recirculate actuator, it controls where the air comes from, inside or outside the vehicle.

The 2 vents closest to my driver side are not blowing as well as the passenger side 2 vents. My car also makes a rumbling noise when turn on the air. When I turn the a/c on high then temperature coming from the vents drop. Need to know which actuator to replace. Could you see the pictures?

The only image I see is the one Mechtrix posted. If you posted any they didn't make it. Maybe shoot some video of the noise and describe the issue in it. That might help to determine the issue. The rumbling happens when you turn the blower on or off or does it rumble only when you have the engine running and you select AC?

Id say before you jump into it id check all fuzes relays control panel because you rarely see both sides go out at the same time I think the actuators should be fine it may just be a comuncation thing or a grounding issue I believe your problem might be elsewhere . And like Steve was asking can you provide some detail as to the chain of events I believe we can help and maybe in the procces save you a little time and money but we need your help also some photos would be great. Let is know thanks

That's under my driver side. Since the air is blowing low pressure on that particular side is that the side we should be focused on replacing?

Before replacing anything watch those actuators as you move the controls, one will be the temperature control the other is the mode control. If they move OK then go to the blower motor and check that the cabin filter isn't plugged with dirt or debris. Then use a mirror to look into the blower motor to see if anything is there. Wouldn't want to replace a bunch of parts only to discover that a mouse had built a nest in the blower (that would cause a rumble and low air flow)

The recirculate actuator is the only one back there and it is on the end of the HVAC case. It only moves the recirculate door.
