C4 A/C ducts recycle fire wall

<< < (2/2)

Bad news Dougie!  :therethere:
I assume your C4 has a mirror conversion as you said you can see the inlet to the fan on the LHS. On the original there is a flap which opens the OUTLET side of the fan (duct inlet) to the plenum so you get fresh air with or without fan. When they flip the heater box the flap, which is mounted in the firewall, gets lost to put the new section in that takes the pedal support and steering column support. All air is sourced from the cabin. If your 'flap' is still there (unlikely) you'll find it towards the centre on the right side close to where the cross duct used to be.
So the cheapest answer might be to fix your air-con or get used to windows and sauna. :tears:

I think you need to change your handle - "to walking encyclopedia". I'm not sure if its thanks or bloody hell I've been Fghhfhfed once again. Obviously  I need to get the A/C going- but it annoys me I can't get it "like" original. The early Comodore AC box was mounted within the engine bay - I wonder.
