[winters coming. no heat. help!]

Fixed it! I found the actuator you described, unplugged it, plugged it back in & it started working. Go figure. Now I know where to look if it does it again. Thank you so much for the help.

Thank you. Now I know where to look. Will let you know progress. Already tried the battery disconnect/reset trick. Didn't work.

Basic heater system. No dual climate control. It has heat on both sides of the heater core. Is the temp door the one right behind the glove box? Because that one seems to be working ok. If not where is the temperature actuator? Do I have to take the whole dash out to get to it? Thanks.

I have 2014 edge awd. Almost fifty thousand miles. No climate control. Last year the heat quit working. A couple of days later it started working again. It was still under warranty so I took it to the dealer. They found nothing wrong. It quit working again & now its out of warranty. I'm a heavy truck mechanic by trade & have always done my own maintenance. I understand how heating systems work. The operating temp is running normal so Ive ruled out the thermostat. I need to know if anybody have seen this before. Where is the temp valve located or does it just have a diverter door? Everthing else is working fine, just no hot air. Thanks for any help.
