Stuck Blend door?
 

'Morning all,

I'm trying to sort out the few niggles that my recently bought 2005 W12 has - in particular, the a/c (still over 40 degrees here in Dubai). While it works, it takes a good while on recirculate to get any cool air - particularly on the driver's side. I already had the system purged and regassed but it still happens. My assumption is a sticky blend door that's letting warm air through but I haven't yet received my vag-com cable or bentley manual to aid in diagnosis- any suggestions?
