Air Con Problems

[Kcboiye]

Lately ive been having problems with my caprice's ac, the face/door vents wont always work as if they are blocked, some air does come through but only very little even at full speed

but the feet vent work fine

so is it blocked? or something else wrong?

vacumm box behind the headunit needs replacing which controls vents, if your missing fan speeds it's the amplifier module between the windscreen wipers under the plastic cover.

Thanks for the info, the fan speeds arent having any problems, just must be the box, sometimes it will be unblocked but most of the time when i actually need it its blocked

hey KCBOIYE.

I got a VS SII SC Statesman.
Aircon regassed 12-18 mths ago and WAS running iceberg!
3mths or so ago stopped pumping through centre/door vents but otherwise good.
(turn on auto and fan was pissy, manual and it would pump ok, but not full strength).
Removed Fuel Pump relay for 3-5 seconds with ignition off of course, and magically it started working again
Was told it could be some sort of Electronics issue requiring BCM reset.

the relay is in the housing in the engine bay in front of the main fuses box.

Damn, now i just have to find where aircon hoses connect through firewall and on engine block coz LPG installer disconnected them during install and didnt put em back (And now they are probably under the cluster of wires installed in the bay)
