Do you know if this procedure works on a 1997 buick park ave with the same climate control. I tried the procedure but it didn't change where the air came out of.

Hi,  I tried the above procedure on my car and it didn't change anything. Any other ideas as to what I should do?

My AC works great but my heater doesn't and i think it maybe this problem. Will this work with the heating unit as well?

Thanks for this very helpful vid! You may be 'just' passing along someone else's hint but YT often yields better search results than car forums. This was my first stop for fixing my heat issues on a Yukon Denali, and thanks to you, it was the perfect cure.
