One method is going in from the front trunk . You remove the wipers and cowel cover and remove the heater core . You have to make one cut of the blend door pivot to be able to remove the blend door . Cover the door with the product you choose and reassemble . This method fixes the blend door that controls AC/heat .

The 2nd method is to go in behind the center console . You remove the two top units of your center stack . This might be your cup holder or radio or HVAC control unit it just depends on how your car is setup . Once you have access to the center vent you make two vertical cuts and peel down the plastic housing .

You can now see the blend door that controls defrost/vent/floor air movement . Again apply product of choice and close it up . Most guys use some type of tape to repair the cuts in the plastic . There are a few articles where guys were able to access both blend doors by going through the dash . I would think you would need hands/arms of a child to do so .

I remember seeing someone post (I think in my local region's PCA facebook group) about fixing his. I think it was a huge job where he essentially removed most of the dash and crap in the cabin to get at everything (not just the 2 doors), but I think any/every junction, but maybe I'm wrong about that.
