Howdy,

I have a problem. I had to replace my HVAC conroller because I broke one of the temperature levers. So I found one on ebay from a 2003 (I have a 2004 LS).

Now that I installed the new one, it acts odd. When it is in the Full face vent position, it blows by my feet and alittle on the windshield. In the Bi-level position is starts blowing on the face and floor. in the foot position it blows fully out the face vents. In the foot/window, its blowing out the face and window, and in the fully windows position its some where else...

I didn't have this problem before. I tried the pull fuse 36 (HVAC B) and relearn. An other hints?

Thanks,
Ryan
