NolletSSS Posted November 19, 2013 Report Share Posted November 19, 2013 Its for the Auto temperature settings. Its a little fan that blows on a temp sensor, I believe its only used in vehicles equipped with the digital control head. Quote Link to comment Share on other sites More sharing options...

The digital control head uses them to start and stop the blower fan based on the temp you set if you are using Auto mode Quote Link to comment Share on other sites More sharing options...

Blown 346 Posted November 20, 2013 Report Share Posted November 20, 2013 (edited) If you do shut it off, your temperature control will not be controlled by the inside air anymore. If you search my name, i did a write up on how to get in between the headliner and the roof so you dont damage or wreck the headlinear, along with the how to stop the fan from making noise where you can hear it run.
