Air CON Recirculation Help

[TKO]

My Air con is climatronic.

Recently When i push the recirculation button there no air coming out from the vents or anywhere else in the car. I would hear the air been sucking at the filter.

The air con works ok when taking air from outside.

Do anyone know what's wrong? Is there a gate or a flip easily check to see it is block or something?

Many thanks.

Hi there,

It may be a vacuum capsule under that dash that has perforated causing a vacuum leak. You may notice when A/c is turned on or temp is set below about 20c when you accelerate the is a reduction in air flow out the centre vents. As you deaccelerate the air flow comes back.

This occurred on my 2000 Caravelle. I picked up an identical vaccum capsule from an 86 PUG 505 at Pick -a-part for $5 !
