Having some issues with the heating.  MFL '00.  Front cabin space on both driver and passenger side blowing cold air.  Rear seat blowers working fine.

Thus:
- not matrix
- not HBV/vacum related

Tried:
- reseting climate, no joy.

Possibilities:
- sampler fan (but wouldn't this affect rear cabin too?)
- servo for front heat FUBARred

Thoughts?

Sounds like a temp regulation flap?

Could be but never had to deal with one.

Anyone have any photos I can use or is it a dash off job?

Heater is split left/right not front/back... either airlock, stat issue, or partially blocked matrix... 

What is temp gauge doing?

What system does it have? Climate/Digital climate/manual control/aircon...

I still have issue of cooler air from rear vents on the 3.2, warm from front. But a damn good flushing of heater matrix solved most of the issues, to the point of red hot at times.

Have you run system up to temp, with cap off, burping any air out?

[Kevin Wood]

Has been reported before.

In fact, I think I looked at this very car, putting two and two together...

I'm guessing it's the blending flaps come adrift each side. IIRC, I tech2'ed the climate panel and couldn't find anything obviously amiss with the sensors and there isn't a sampling fan on the FL, IIRC.

I think you can just about get to the blending flap linkages by reaching up from the footwells, without removing the whole dash.

So car is early facelift with proper system

[Gaffers]

Yes, has the FL Climate panel.

I will have to see if I can get my bear paws up in to the area.  Is it better drivers or passengers side?  ISTR that the pipes come down the driver's side and thus from the passenger side it might be best. (just trying to avoid the inevitabel swelling from the uticaria as possible)

Similar issue here since changing the water pump, where the rear vents blows cool air while the front blows warm on the sides and hot in the centre can also hear some gurgling around the radio area. Probably an air lock as was perfectly fine before just haven't got round to sorting it... Might have to lift a finger now it's getting cold

That helps a lot.  But upon reading I notice that these issues relate to one side blowing warm and the other not.  Mine is the entire front cabin, but the back is ok.  I shall check anyhow

Humm interesting 

Try as above running up to temp with cap off, squeezing getting air out.

When I flushed my heater matrix it was quite clear, but did help with cabin heat

I did, when I flushed it within an inch of it's life.  That said, I did not put much pressure down the matrix pipes for lack of a suitable hose setup chez Guff.  I might have to give that a whirl tomorrow morning.

[tunnie]

Sticking hose in hot water did help, but not a great deal. Hose was very old, I ended up leaving the hose connector thingy on. I found that much easier to keep on the matrix pipes, also reversing the flush too, quick to swap them around.

I just disconnect the other end of the hose and a copper pipe reducer to connect it to the hose.  Then it's 3 Bar of flushing
