Air conditioning

[Petrolhead]

Hi!

My 62 has the factory optional air conditioning. It works well on cold, but won't blow out hot air. The hoses appear to be connected properly, I can't locate an on/off tap for the water circulation, am I missing something?

Thanks

Alistair

Possibly;

• Inoperative/frozen hot water valve
  
• Blocked heater core
  
• Air pocket in cooling system or heater core
  
• If valve is mechanical, improperly adjusted cable
  
• If vacuum, loss of vacuum signal.

Thanks Kultuz, #5 sounds likely as I have been working my way through various dicconnected vacuum lines

Will check the trusty manual (schematics look a bit daunting though!) and work through your suggestions

Cheers
