For the love of me I can't see what I'm missing.

Please note - I am not a mechanic or expert in anything.

 

If you have not already sorted this by now . . . 

 

What manual are you working to, is it for that particular installation, can you put up the manual instructions (pdf?) for others to see if you might have missed something.

 

I usually find it's a fixing I've missed or forgot about - I was once struggling to get a brake drum off tapping it harder and then I noticed I'd only removed one of the two plainly visible screws, a job I had done a good few times before so knew there were two screws, so how could I miss it but I did.

Sadly the exact hvac unit is not doccomented in any manual.

Finally! 

3 hidded screws underneath the dashboard. 

 

Well done.

 

I was going to suggest taking lots of photos and then zooming in on them, or using a cheap endoscope on your phone to get in better to where the fixings might be.

 

On MGBs the heater box is clearly visible in the engine bay and held in by 5 or six screws one being under the circular sweep of the fan housing part and in decades I never found anyone who knew how to get that screw fitted properly yet the factory managed and so did many restorers.

 

Now the matrix is out you can clean it internally, it looks clean externally in the photo, and flush, back-flush and flush again with a garden  hose.  The way you look after your car it's probably quite clean internally any way, I've seen some that perhaps just used water at some time(s) and they never fully stop giving out some debris.  We'd do a small vacuum test before reinstalling even though it was rare to get leaks on them.

 

Good luck.

Thank you for this, very interesting read. I didn't know they had microswitches in heating/distribution knobs, that's more advanced than the original solution. And the battery bracket for RHD market is interesting, too. I wonder, if anyone has ever see one installed 😄

I learn about these relays ''with the hard way'' years ago, i didn't knew their existence and only after 2 times the radiator fan stopped working (different days at summer) the mechanic informed me about them.

Are below my strut brace behind a black plastic cover, not visible.

No problem I thought it could be interesting and helpfull, yes this system has almost all flaps operated by motors except the feet air control and heat mix (the one that was stuck).
What a pig of a job to do though.
I've also made a video which I will share when I edit

Congratulations!

After looking to the Alex system pdf. I see, you've dealt with a custom A/C system. Good work!

Thank you it was a pig of a job
