98 Dak, AC/Heater Vent Controller Not Working

While you are correct, you're answer leaves a lot to be desired. I got a much better answer on another forum - there's a vacuum supply line that feeds through the firewall which I had fed back through but forgot to hook up.

FYI In the short amount of time I've perused this forum I've seen some of your answers/replies and they are always short and lacking in details - as if you're assuming you're talking to a professional mechanic which I doubt many people on here are. I'm quite proficient - I've rebuilt an engine, replaced an engine and most other parts but since being a mechanic is not my profession it's hard to keep up with everything new in cars. So in summary, if you goal is to help people, a little more detail in your answers would be much appreciated by everyone I'm sure.

It's fixed, but not because of your answer. I didn't say anything about 500-word essays, but had you said, "sounds like there's no vacuum, check the connection through the firewall to the brake booster, then it would have meant something.

Well, you know what they say about assumptions.
