Well i haven't paid much attention to it cause I've been trying to get more important things straighten out but the heater in my 87 t2 dont work. i switched the controls and the little black box with the controls with my old rx7 cause i knew they worked but still no heat. only thing i didn't switch cause i couldn't unplug it is the chip board that everything plugs into (controls and that black box) What else could it be whats usally the first thing to go that would cause no heat? everything else works.

 

1) AC Logicon
2) Air Mix Motor

A couple of times I have seen the air mix motor plug come loose after someone has been working in the dash. Might check to see it that is the case with yours.

 

I also think it may have come unpluged. This as well happened to me. I had to pull out my dash to get to the connection. What a pain in the _ss.

Good luck (hopefully it's someting a bit more simple)

Most likely the air mix motor. It has crapped out on both of my '87s.
