Recirculation, air directional controls doesn't work

[lord volvo]

Hey all.

Been getting acquainted with my "new" 2000 S40. Happy overall aside from a few things such as the recirculation button doesn't shut out outside air from coming in, and the air directional dial doesn't do anything. I don't hear any clicking noise as in slipping gears so maybe the previous owner disconnected the system as I've read elsewhere due to the clicking gear issue.

The blower and temp dials work fine as does the AC.

Mine is the electronic HVAC system.

I know my 240's recirculation and directional controls are vacuum-driven and somewhat easy to troubleshoot and repair, but vacuum-driven controls are from another time.

I've read other posts on this issue in other non-S40 vehicles about either the motor that controls flaps is broken or the flaps themselves are not connected, and the nightmare of accessing those items since they are buried in the center console. I've read of cutting a hole in a plastic panel behind the glove box which is something I really don't want to do unless I really have to.

There are a few pre-2004 S40s at my local pick-n-pull; hoping I can get parts from there before buying new and/or paying someone to fix it.

Any advice on this would be appreciated. Thx.

I think there were others that experienced problems with the S40 ECC.
Pretty sure XeMODeX had rebuilt units for sale for around $300.

Mine still works ok regarding direction, but the fan speed sometimes has a mind of its own.
Sorry that doesn't help much for your issue.
