My 2004 has had no heat for about 4 years and I'm finally fed up and want to fix it. I've seen the videos of how to rig it manually pulling the lever down on the blend actuator to turn the heat on and it still blows no heat. What other areas could I check to see if there is a different cause for no heat. Please let me know thanks. And if anyone is local to Kennesaw Ga and could help id appreciate it.
