I have read alot of posts from owners of 2004 avalanche with problem of AC blowing hot on one side intermitantly. This is obviously a design flaw / bad component and one that pisses me and others off! Should be a recall. I still don't know the fix without having to spend hundreds of dollars on actuators that may or may not fix the problem based on posts here. What is GM doing to satisfy their customers? Why would I buy another GM product with such poor quality from a realitively newer vehicle (2004)?
