Does anyone have a picture of the non AC controller? I'm pretty sure they're different but not sure. I want to be sure before I go spend $100 on a non AC controller.

why not go to the junk yard and spend 5 bucks...plus beware, depending on the year, they may be different.

Controllers are totally different, at least the ones I've looked at in the JY. The non-A/C controller uses cables to operate the blend doors and the HVAC controller uses vacuum acuators to operate the doors.

I have the non-A/C heater Box with A/C controllers and it stay stuck on Defrost, which i guess is most important around here. Laughing

The box and the controls dont really have much to do with it. If you are stuck on defrost, you likely have a vacuum leak somewhere.

it's probably disconnected from when i took it apart a few years ago

with the non-AC controler you will have one less fan setting, as well as the fans being physically different in size. IIRC, with the 82-89 control you should have 4 vaccuum lines and 2 cable controls on the console as well as the two the cable controls for the air vents that sit directly underneath the steering column.

@ nonsense kid: from 82-89 the non-AC cars got a cable-driven heater box, so the entire thing: box, controller, vents, was radically different than the AC cars. In '90 they switched so the non-AC cars got a vacuum-driven box, with vacuum controls. I believe (but am not certain) that in the last three years, the controllers are interchangeable. I would make nice with Luke and see if you can pop his out for a quick look.

Also, $100, wtf? I bought my last MOTOR for a hundred bucks. Smack!

@ James : Seems to me if you installed a non-AC controller in an AC car, you would have a lot of vacuum lines left over. Rolling Eyes

Its for a 91. And I'm helpin Luke with his swap next week. Maybe we can look then. hah

But yeah the A/C was all vaccum driven. There was one cable and I think it was for the hot to cold.

Time to head to pickapart! soon enough. haha

Pick n pull in sherwood has a non ac car. Probably a mid 80's version. Had the earlier front end on it.

Well Luke confirmed. We pulled out the non AC unit and it was in fact different. Time to head out to the junk yard.
