Anyone know why my recirc button doesn't work on my climate control? 98 ClK 3220. Thanks.

 

Does the button light up when pushed? the recirc wont work in defrost mode. you don't really need the recirc anyway.

 

Yes. The button lights up. I'm trying to get my climate control to work the way it is supposed to work. On a hot day, it would be beneficial to use recirc to recool the interior air until the interior cools down.
Do you know how to recalibrate all the flaps, so they do what they are suppose to do? When I use the directional button, the air seems to come thru the front vents even if I send the air to the windshield only. Thanks.

 

Yes you can go to the dealer and they perform a stepper motor normalization and will test and check the operation of the blend flaps.
