When my 156 V6 reaches operating temperature only hot air comes

Resolved Question:

When my 156 V6 reaches operating temperature only hot air comes from the ventilation system. The air con. is definitely working but the temperature control knob has no effect. I believe there is a computer controlled flap that I assume has become stuck so that only hot air reaches the cabin. Is it a simple job to fix this (my hands are very arthritic and don't know a spanner from a screwdriver - I just continue to revel in driving this lovely motor after 15 years and 105,000 miles) or do I need to take the car to an Alfa servicing establishment?

Hello and Welcome..

My name is XXXXX XXXXX Im happy to help / advise you.

You are quite right in your thinking - this is controlled as you say - and very often its a blend door ( flap ) problem that causes this - or the drive motor for it -if its the electrically controlled system... If not, then you still get the blend door issues, but they are cable controlled - and it can then be a cable fault.

It will need physically checking / looking at - and it does mean getting right down and up under the dash. If you struggle as you say because of the arthritis, it really isn't the job for you... I would say though that any good local garage can do this for you - and this may well be a lot cheaper on labour costs than a dealer.... But yes, it needs the physical checking as above to determine exactly whats happened there - it can be either as Ive said -and then on to repair as found...

So thats the way forward on this one now .. Let me know if you wish how you get on..
