i have a dual automatic climate control system.the re circulation function comes on all by itself and fogs the windows. i can not switch it off by hitting the re circulation button. i have to hit defog and it goes off but comes back on in 2 to3 mins


I need a little more information in order to help.

What temperature do you have the controls set to?

What is the outside temperature?

Does the problem occur during the day, night or both?

Do you have the system set to Auto?
