1994 2 door Blazer
 

Just have a few questions regarding my new (to me) Blazer.

Question 1 - K5 Blazer - Barely have any heat when on full blast. Air is luke warm at best. AC works fine.
Question 2 - K5 Blazer - Rear lift window will not open. Changed the struts. Hear the release but window will not kick out. It will open if someone is there to grab the handle and pull. Am I missing a spring or something to get it started ?

Other than that I love the full size 2 door Blazer (Sport).
