Heater issue

Hey guys, Im having an issue were the heater wont blow any hot air out the vents and I wouldnt mind having better heat since the weather is -15C (10F) lol

The heater works as I get hot air that raises up from the dash onto the windshield, but thats pretty much it. The blower fan also works and increases in speed as I change the speed setting. What I’m thinking is the vent doors may not be functioning anymore, but before I start yanking everything apart Id like to know what you guys think it could be?

Well I found out that the previous owner installed the wrong heater motor controller, theres a 3 wire controller (I think from a civic) and its supposed to be a 4 wire. This weekend I’ll be taking a trip to Pick n Pull to grab the proper controller.
