Default Climate Control questions

2000 Outback, manual climate control. EJ257 swap with ecu/ecu harness.

All fuses are checked out and good.

The problem I'm having is the climate control is stuck on defrost, kind of. Air comes out all of the vents a little bit but mostly out of the defrost vent, no matter what the dial is set to on the dash.

Can anyone school me on how the manual climate control works in these cars? Is there a control box behind the dash that's vacuum or electrically operated? Would like to fix this before the snow flies up here so I have proper control over fogged and iced windows!

Thanks.

It's basically a wire and pulley system. There really isn't anything electronic about it. When you move the dial, it manually pulls a cable to move stuff behind the dash to direct airflow appropriately. I'm guessing the cable came undone or something broke. Sounds like you need to take apart the dash.

IIRC, part of the cable is on the passenger side foot well, and likely became jarred swapping the ecu.

Actually I'm pretty sure only the temperature part is controlled by a cable. The "zone" selector is electronic. So your problem is the electric motor that selects what zones get the air flow is getting stuck.

It happened on my '97 BG Wagon and I could get it to work by tapping on the side of the air box or the dashboard (by tap I mean hit really forcefully). Trying changing the selection and then hitting the box that houses the evaporator, it's attached.
