heater box

‘93 2.3 ranger. When I started my truck this morning(noon) smoke billowed out of the vents and smelled like a wood fire. Leaving work now, no smoke was noticed, but it still smells like wood smoke. any suggestions on what this could be?

My heat will only work on driver side and not passenger side. has anyone run into this issue? It can be set on dual or single still then same thing.

Hi i got a 97 stx 5 spd and the broken blend door that everyone gets is getting fixed finally. I was wondering if anyone here can help with the last part of the fix. Im trying to replace the door without cutting a hole in the box like all the videos on youtube show and even with the doorman...
