Has anybody changed a stilo heater motor ?
Is it possible to get it out past the steering shaft and pedals ?

Sure. Do a search and you'll see people who have removed it. Tie the clutch pedal down to the brake tube which goes across the car.
You can slide off the steering connector if you want to for even more room. If you really are a big bird then you can take out the driver's seat in 15mins (provided it's not the electrical type moving seats) and then you can lie out in comfort
Just remove the centre console side panel for access (see how it's done in the picture)

Excellent - will try over the weekend - Many thanks
Does anyone know where the temperatur flap thing is? The gadget that controls the airflow of cold and hot air must be stuck or damaged. The motor itself seems fine, but the airflow and temperatures are just hot all over, and turning it to "low" only activates the centre vents with semihot air. These should be freezing cold... Not even the -13C comes in without open the doors (windows are frozen stuck...).
It's like a sauna in there after 10 minutes.

Do you have climate control/ manual air con or no air con?
Full dual zone climate control. Used to work 100%. First symptoms was during summer when suddenly hot air came out of the left center went and cool (aircon) air came out the right center (is it spelled center or centre???) went. This is a dual zone assembly, but it was not set to "separate". This is actually great as I like it cooler than my wife, and the magic thing is that it works 8not any more though). Well, a stop and restart cured it then. But now... no cold air at all. The clutch on the aircon engages, the gas was refilled, and the snowflake is on - which is great during winter to dry the cabin from moist - as we usually are snowed down or damp from ice scraping when entering the car.
This is much worse than the Ritmo Abarth from -86, where you either had hot on full (as the resistor was broke) or windows open fully to make a dual zone climate condition.

Being too hot in these kind of temperatures is interesting (we're having a very big freeze, for us anyway, in the UK at the moment)
Isn't there a a self diagnosis for the climate control? Reason I ask is that you need to work out whether it is a temp sensor not sensing it IS hot and adjusting flaps and actuators accordingly or whether it is flaps and actuators not moving (ie broken flaps or actuator not working)
If it's a real problem you can always clamp one of the heater pipes to the cabin. That'll stop all coolant heat getting in and you'll freeze soon enough
Check if the aircon is putting cold in by carefully feeling the air con pipe under the bonnet where it enters the cabin. This should be too cold to touch for long of course. Aircon isn't usually allowed to work if temp goes below a certain amount +3 degrees C I think it is

Well, being -10 C at the moment everything feels cold... How to examine if the faults are the flaps, sensors or the actuators I have no idea of. And how do I really get to these things. Electricity is not my area... I have changed the pollen filter, so I've been around the footwell before. I guess the motor must be there somewhere, but that one is working like hell. Short on cash and a wife that won't have anything wrong with the car is kind of a conflict...
Minus 12 here too last night.
You have lots of little motors like these moving different flaps and blenders
But just what operates what you'd have to find out
Isn't there an on screen self diagnosis readout of the climate control to point you in the right direction?

There is a "Secret Menu" for the climate control but nobody seems to know what all the codes mean. I've also seen some discussion that suggests the codes could be different for different countries.
I also have Italian, German and French language versions of the code list.
Climate Control Access Menu
First, turn on the engine.
1) Push the HRW button for 5 seconds. All the elements on the display will show up then disappear.
2) Push the HRW button again to go up the menu and the OFF button to go down the menu. The menu is from 00 to 99 as shown in the driver side temperature digits. The value is shown in the passenger side temperature digits.
3) To exit the menu, press the HRW button for 5 seconds then release.

For starters, where or what is the HRW button. Haha. This is going great.
Thanks for the amazing list by the way. Olympic game of numbers. But how do I find what is wrong? This will be th idiot vs. the climate controller.
Some german words have sneaked in there...

Gotta go, have it fixed by the time i get back

These are the values I got. I have no idea of how to interpret them. Maybe someone could point me in the right direction. Car had operating temperature at idle. Outside temp was around +6 C.

Well these are the ones that look suspicious to me
So now you know it's the actuator and not the temp sensor giving false data
So i'd find the motor which controls the mixer or blender flap and check connections - clean contacts with contact cleaner and see if it makes a difference

I saved these code lists months ago with the intention of translating all the language versions to try to produce a more accurate English version. I haven't even looked at them since I found them so I still don't know how accurate they are or what they mean.
From your readings Morty, it would seem as though some (if not all) of the codes are wrong. e.g.
67 17. Driving speed (km/h) would suggest you were driving at 670km/h.
I've seen elsewhere that some country's versions use code 40 for Driving speed km/h and that you need to add a 0 to the result.I've also read that some versions use code 37 instead of code 27 for Engine speed and code 24 for Blower fan speed. These and Driving speed should be easy enough to confirm.
I think we need a Fiat Tech to sort this out for us.
The list I posted doesn't have 73 to 99. Did you get yours from another source Morty?
Dave.
Do you know how I can get there? Is it from the sidekick panel in the footwell?
Yes from the centre console side panels, mostly lh side. Have a look at the drawings i posted earlier
Didn't understand it was there. This means I've got the steering column and all pedals as obstacles.
