i have a brisk cold breeze coming through the glove box when on highway and doesn't allow my cabin to stay sealed, any suggestions? Thanks

 

This is where your cabin air filter is located. Drop the glove box, unclip the shock on the right side of it, drop it all the way down and remove it then you can look where the filter is to see if something is stuck open or out of alignment.

 

Is the re-circulation system working? Make sure you have the light activated on your climate control ****?

You need to ensure the trap door is closing when the recirculation light is on
