The numbers aren't the same. Those two at the top are the same: 46723329 (distribuzione) and the lower one: 46723328 (miscelazione), substituted for 77362410.

ok new update and a problem i came up with.

The motors came and the gears but none of them contained the white adapter thing between the motor and the gears.( i assumed it would either come with the motors or the gear package)

its the white thingy in this pic. i coulndt really find anything on eper except 46723463 which is described as a lever but the strange thing is in the diagram, that this is referred to the defrost and direction motor only, even though the left temp control motor also has one. Any ideas from anyone what part number it could be?

Part number 46723463 is the 'white adapter thingy' as you put it...

thanks alot yellow peril!!

Hi Guys,
Long time ago I started this tread. At that moment fiddling around these bits seamed to complicated for me, and my AC worked fine (temperature-wise) so I lived with it blowing conditioned air only at my face. A month ago it stopped working completely (no cold air), so I decided it is time to see an AC expert.

To remind you all, it is a LHD Stilo, 1.6, 3 door, with Dual zone climate control.

They changed high pressure switch that was (literally) blown and refilled the whole system. Ice cold air started flowing again, but then I decided I should ask them to sort out my actuator motor problems. They said two of the motors are busted, direction and driver mixture for the legs. After that I am not so sure what they mean, as the last one does not exist under that function/name. They had in stock the distributor motor and they changed it, but they mentioned that they needed 6 hours to get to it, as it was located on the top of the AC casing and that they needed to dismantle the whole dashboard (evidence of that was sunlight sensor that hasn't been returned properly and bent plastic of the passenger windscreen blower).

I am asking myself and the Fiat community, was all that dismantling necessary to get to this motor?

The mixer motor they said it is easily accessible and they will change it next time I find time to drop in.

Unfortunately, at the moment I am not able to test the system, as my car suffered other problems just two days after these repairs were done. I described this in my other post:

https://www.fiatforum.com/stilo/271265-battery-alternator-problem.html

Also, it was suggested to me that dismantling the dash might have cause the other problem... Will keep you posted on both topics...

Thank you all in advance...

stilo belgrade the distrubutor motors are 5

1 for outside air
one left and right temp air mix motor
one upper windshield motor
and one motor that controls feet and console air supply

all of the motors except the outside air can pretty much be changed without removing the dash but its a pain of a job my back was in pain, i had to shove my head at drivers foot well and had to twist my arms and painstakingly try and remove the screws which has no room. im sure that standard garage safety rules dictate the dash must be removed.

Haha, pretty much the same method I used. Use a bench that has the same height as the doorsill, this makes sliding in easier - head on the throttle pedal. I can understand that garage work environment / safety rules requires a dash removal for the job.

Thanks Guys,
You restored some of my confidence in the mentioned Garage.

Now I have to see how my other problem resolves, and whether it was caused by dash removal and refit procedure.

Thanks and regards!

I have serious problems getting the lower driver’s side motor out. How did you do it? Does it have 3 screws? I can only see two, or more like nuts or bolts. There is a little peephole in the A/C left side so I can actually see the lever move. It's much easier on the right side to watch the other lever. Since the lever moves, it's either the flap inside, or the motor that's having problems. But I can't get the motor out... Am I missing one screw?

Then i did the same with the left hand side dual zone motor and watched it. it went counter clockwise stopped then went clockwise for a very short bit and stopped. Pay attention though that the motor does have a protecting mechanism to not brake the inside flaps of the aircon in this even thats why you will see that on the outside of the motor there is a plastic protruding right beneath it. this blocks the gears from going more than a specific travel and the breaking of the gears is to protect the inside flaps i assume.

hello morten im replying here instead of the email. all of them have 3 holes for screws or that nut/bolt type screw on the motors so look hard to find it. be very careful not to drop it because i cursed and cursed for hours till i managed to hunt it in the crevices of the a/c with a magnet. make sure when you put it back in it aligns with the lever part.

This fix looks very complicated and tricky. If you're not technical minded, don't have the time, what other options are there for fixing this pathetic Air con on the Stilo?

That's simple: Let someone that gets money for fixing other people's cars fix it for you.

I have a similar but different issue - I get no air flow down to the floor vents, front or rear... this is on all sides, so I can't see it being one of the Bosh units. Is there a way to reset/recalibrate the whole system to see if it rectifies?

This is the self learn procedure for the climate control. May help.

CLIMATE CONTROL SELF-LEARNING PROCEDURE

The AUTO and MONO buttons must be pressed simultaneously within 40 seconds of the ignition being turned to the ON position in order to active this procedure.

A few seconds later a figure will appear on the display (in place of the driver's side set temperature) which will count down to indicate the time remaining before the start of the procedure. At the same time (i.e. whilst the count down is taking place) the previous self-learning status is signalled on the passenger temperature setting:

'1' flashes if the previous self-learning procedure failed.
'0' indicates that the previous self-learning procedure was successful.

This procedure is not carried out if at least one of the above mentioned buttons is released whilst the figure on the left hand side is not zero (this is designed to check the outcome of the previous self-learning procedure).

Exiting the procedure zeroes the 40 second counting period from when the ignition is switched ON, to allow the procedure to be repeated without having to switch the ignition OFF.

Each time a new control unit is fitted, the flap actuator learning test must be carried out using the diagnostic equipment and the unit must be personalized through programming.

Is there anyway I can bodge this? Can I stick up arm up the dash and manually open the vents?

Sake the side panel off, remove the pollen filter to unrestrict the air flow... then click the demister button to force full volume upwards and look high up behind the back of the pollen filter area at the same time - you should see a white box with dome gears and metal rods - just give them a bit of a nudge and keep altering the air direction buttons, se eif you knock it free - worked for me.

An addition to this thread. How to remove the right temp actuator. This is from a left hand driven car, so it's the passenger's side... The same actuator and function also exists on the other side of the console.



1. Rip of side panel in the footwell (pretty much the same on both sides by the way). This reveals this arm and actuator above. Actuator has 3 self tapping bolts (into plastic) and have the mysterious size of 5,5 (metric).





2. Pop off the arm, to prevent unwanted destruction.





3. As it is quite impossible to get to the 3rd bolt, removal of the glove box is necessary. And it saves a lot of time.





4. Location of bolts.





5. Difference in design and producer.






6. Change the pollenfilter while you are down under, twisted and in pain.

where and how did you get this similar dense motor out of interest as i need one


many thanks jon

When your order an actuator you get a Denso one. The old Bosch actuator is replaced with a new part numbner...

i can't find it on eper don't suppose you can remember the fiat no can you and also do you no part no for driveshaft that fits in to the moter

many thanks jon
