Air con feeble when on 'Lo'
« on: 28 April 2009, 06:36:50 »
Having been using the climate to great effect over the winter to keep us all warm I've been using it more at lower temperatures as it's got warmer.

Sometimes it doesn't go cold at all and others only after a while (20 mins).
It was regassed last june but never really gets cold. Air con service coming on I think - but what do i need to look out for?

Any ideas? (search didn't reaveal anything)

Just check with the car running and the CC on Auto and Lo that the air con pump is running (passenger side of the engine near the bottom), if it's not running then it could be a leak as it'll shut off if the pressure is low.

Or dodgy electrical connection to compressor! Possibly

I've had similar problems too, but an AC service sorted the problem

Also check, when on low (and outside temp above 4C) that you have a vacuum to the top of the HBV...
