Does the the flexible black tube connected to back of the right side of the digital climate control unit affect the amount of heat you get from the heater? I forgot to reattach it when installing a stereo and now it seems the heater isn't working as good as before.. I used to turn it up to 75 to get warm/hot air.. Now I only get hot air when i turn it up past 80. So what does this tube do?

 

Re-attach it and find out.

 

it draws cabin air through a small temp probe inside the climatre control unit. The control unit uses the temp measured to automatically adjust the cabin temp.

 

I will re-attach it once i get time to go to the dealer to pick up some bulbs for the climate control buttons. So i guess since the tube is not attached, it does not sense that the cabin is cold and won't give me enough heat? I guess this makes sense since the tube is left hanging somewhere behind the stereo where it is warm.
