All I have a 69 280 SL that while cleaning the drain plugs I noticed that the driver side heater flap is broken at the wire cable and plastic pc and the heater control valve was also disconnected from the flap and could not be moved by hand at all. My question is where do I find this flap and how do I free up the heater control valve for it can function and don't break the new flap? Thanks for all the previous help from many of you.

On the firewall Left side there is a largish rubber grommet that covers an inspection opening giving access to the heater valve. Suggest you open it and check if the valve is stuck, usually the cause for the broken cable. Use a WD440 type penetrant on it to see if it frees up as a starter.

Yes the heater valve should be freed up first. I remove the heater hose going into the firewall to the water valve. You can then spray the penetrant directly into the valve itself. Warming the valve with a heat gun also helps before attempting to move it. If your plastic heater flap is broken, remove the little intake air hood, in front of the windshield, you then can remove the flap and repair or replace it. If the heater water valve is badly stuck, you will have to remove the inner cylinder and clean the bore and the cylinder itself (steel wool works good). Do not drop any parts when working on the water valve, also do not push too far downward on the cylinder. It can fall through into the heater core.
Let us know if you need to remove the cylinder in the heater water valve. Additional information will follow if needed.

I had the same driver's side broken flap because of the heater valve stuck.
I discovered it after dismanteling all the dash commands and the heater blower.
I used epoxy resin as a glue and it worked well considering it is not a visible part.
I don't know if the part is available.
Good luck as it is a very deep work and those who went there remember it...
Hope this helps

Hi Fred,
Good to hear that you are still with us in sunny Noumea. Like you I had a similar problem with the heater flat lever and I also reattached it with epoxy - works perfectly and is probably stronger than the original.
BTW, did you buy that other rescue car you were looking at earlier this year?
cheers

Thanks to Fred, Garry, and Joe for your replies. Just when I thought I was in the clear in breaking loose the control valve the worst night mare happen a LEAK developed in the heater core. OH CRAP is it the mercury metro grade or what!!!!!! Now I must go where few have been wish me luck it appears it will be a long hard winter....
-
That is the worst nightmare and abig job. Better to find it rather than a wet floor is one way to look at it. You will get the heater slides working by the time you are finished.
When doing the engine bay in mine the heater tube through the firewall got knocked off.
Unfortunately for you its back to basics and stripping the dash board I suspect.

Gary,
The other option is having another elbow inserted into each arm - this might reduce the time for getting the core out
-
Got the core out!!!!!!! Now are there any new ones out there or do I have to have the old one repaired????? Also can I find a new control Valve where all the trouble started.... Thanks for the info in the Tech guide and the replies to guide me through it.

I think you will find it is a whole lot cheaper to take it to a radiator repair shop and have it done and having a go at repairing the control valve will save you lots of money.

Thx Garry will keep you posted.

Hi Georges nice to read you too.
Amazing to see once more that what happens to our treasures happened also to many others and that they succeded in fixing the problem. Helps to feel less alone...
To answer about the "Bordeaux dying pagoda" still impossible to get in touch with the owner. I don't desperate.
Kind regards

I will soon need to do the same repair as my left flap is broken. Meanwhile I manually closed the heather valve. Should I drain the cooling system before attempting to remove the heather valve to service it?
-
Would anyone reply?
-
Hello Dante,
Just loosen the radiator cap. The heater valve is very high up in the cooling system and only a slight bit of coolant will be lost. If you want you can remove a little coolant from the system before you begin.

Thank you very much Joe. That will be the first of my next winter jobs on my Pagoda!
