After going in limp mode last year, only the front driver floor vent and defrost blow out any air and it's intermittent and very weak only comes out at the highest fan setting. The front vents and all other vents blow out nothing at all. When the air does come out of the slightly working defrost and driver floor vent, it is the correct temperature but very weak and intermittent.

This happens when the MODE actuator goes out, but you might be able to reset the system by following this guide:

If that does not work, you will need to replace the actuator. They call it an "Defrost Vent/Register Door Actuator"

Here is the location which you will need to remove the glove box for. Check out the images (below). Please let us know what happens.

Once I remove the glove box where in reference to the glove box is the actuator located? I couldn't find it. Did I mention it's manual controls for the A/C settings also.

Okay, I thought it was an auto HVAC system. In this case the actuator is on the drivers side above the accelerator pedal. Check out the images (below). Please let us know what happens.
