help with 3.2 carrera heater

[james280779]

Ok I have done my research and I now know that the flappy part in the heating system is stuck open, this is the bit that diverts heat from the exhaust into the car for windscreen demisting, feet heating etc.

Now I couldnt find anything pointing out how to fix this - even haynes manual didnt help. I presume its easy but how do I get to the paddles to shut them.

I live in the tropics so I dont need heat at all - its 30 degree plus everyday - closer to 45 with the heat stuck on!!

I am literally melting

thanks

You say the flapper box is open? This being the case then the hot air will be dumped onto the road and not enter the cabin.
Each flapper box/vent is operated by a cable which is push/pulled by either levers in the cabin (SC) or servo's which in turn are operated by the heating thermostat in between the seats (Carrera 3.2).

If you haven't already I would check the both sides - I recently had a sticking flapper vent which was clogged with road dirt so wasn't fully opening and letting warm air into the cabin.
If the vent is not fully opening (some residual heat) then could be road grim, cable sticking or servo's not correctly.

Let us know how you get on...........

It has to be the flapper box as there is no sound from the fan - It is heating the cabin so whichever one, what I need to know is where they are located and how to access them to open/close.

Each flapper box can be accessed from underneath the car. You'll need to get the car on ramps or a set of jacks and axle stands (make sure the car is chocked on the front wheels and axle stands are in place in case of one of the jacks failing).
The flapper boxes are located forward of the rear wheels, up high - likely you'll need a good torch of inspection lamp to see them. Another way fo finding them is to follow the hose from the front of the heat exchangers up into the car.
I have enclosed a pic showing one of the flappers and it's assembley/location.


The pic was from an american forum, Pelican parts which has a ton of info on heating/ventilation problems and refurb.

Mine do this and I found that I can just reach up and adjust them, it appears that event the smallest amount of overlap can cause heat to come forward.

beautiful, that photo was invaluable
