I had a problem where my 2014 edge se would not switch from cold to heat. I changed the blend door but that did not fix it then I found you guys and watched a video here how to reset the hvac control module by pressing buttons on the heat control panel and that worked so thank you very much forum members. My problem is I have had to reset it about 3 more times since so my question is is there a permanent fix and how many times can you reset it before it doesn’t work anymore?
