I needed to change the evap in my 87 1/2 ton truck. I went to a local wrecking yard to remove one to see what was involved, when I did I noticed that the evap on that truck was packed with dirt.when I pulled mine out it was packed with leaves dirt debris. And without pulling the evap there is really no way to clean that area out. The blower works much better now and ill bet the ac will to
