Almost certainly O rings. Can be done without removing dash, took me a morning, would be quicker next time. I made the carpet wetter with biological washing powder in hot water then dried it with a dehumidifier and the aircon.

Wet or dry vac then a dehumidifier. O'Rings can be done without removing dash.

It's always easier second time, what takes most time is drain/refill.
First time round i followed a mixture of the short cuts but never cut any pipes.
Second time I had some very long screwdrivers handy and did it from the radio hole (radio out) minor problem you cannot see but plenty of photos available even managed to take some with auto focus small camera so I could see how I was doing.

Best tip is to loosen/disconnect both pipes in engine bay and have a helper there, makes it fairly easy and quick.

Special tools needed: Very long screwdriver.



This is photos from first time where I drilled holes, not needed second time round.

No need to drain and refill. Clamp the pipes and disconnect them, then put a rag around an airline and blow gently into the pipe that goes to the top of the matrix to empty it. Do O'rings, reconnect pipes, unclamp run engine and top up.

Oh dear now you're saying that, I didn't drain alot only what came out of pipes when disconnected.
And one must be so careful refilling the sensitive beast, not that it's difficult but must be done right or else:boom:

Mozz,

I'm more than happy to post you up the very long PZ2 screwdriver you'll need...unless the original screw has been replaced in the past.

I bought it to do this job, no need for you to buy one too.

PM me an address and I'll get it in the post.

al see your messages cheers

I bought a screwdriver from BQ of all places for 6 quid but on rebuild used a stainless allen bolt ( supplied very kindly by Irishrover) also if the ducts are cut in the right place it allows the blend motors to be replaced in about an hour and a half
