Air only flowing to windscreen, not blowing through passenger vents or footwell.

Bravo 2008 with the auto climate control. Unit indiciates footwell/Vents but flow remains to screen even when not selected.

Believe it is most probably the small electric servo motors drive that drive the flaps.

Anyone know the location of each or tips on replacing or have any good advice?

Cheers

Re: Air only flowing to windscreen, not blowing through passenger vents or footwell.

I had this problem and solved it myself.
Te problem most likely is that the plastic pieces connecting the motor to the flaps. Cheap item hard to replace.
Bad news: it's about half as bad as replacing a clutch ..only less room.
It might be easier for you as the motors you are after are on the passenger side for the right hand drive models.

To do it the normal way you need to take out the doors, the seats, the steering column, the head unit, the dash display, the arm rest, the center console, the dash, then a metal brace along with the ac unit( the big thing that has the evaporator and the heater and the flaps..etc). The elearn manual says to remove the coolant and the freon as well.
When you get to this point you actually have access to the flap motors.


What i did ( for a left hand drive car):
I took out the steering wheel column and the plastic covers ( you might have to remove the glove box..and other panels in theway) in order to get to the metal strut piece it's made out of aluminum; then i drilled a hole in it in order to get some access to the screws thats ecure the motors to the unit there are 3 screws for each motor.
Then I spent 6 hours on my back under the dash trying to get the screws out, used 1/4 sokets with flexible extensions and u joints and extensions...etc

Re: Air only flowing to windscreen, not blowing through passenger vents or footwell.

Have you replaced them with original parts or somehow reinforced them? I mean...they are bound to fail again and that's what stopping me from fixing mine. If I disassemble half the car, I want the fix to be permanent.

Re: Air only flowing to windscreen, not blowing through passenger vents or footwell.

I repaired the original broken part wit a piece of iron ( a screw ground to shape so it wold fit on one side inside the motor and on the other side inside a cutout i made inside the cup-like piece.. and use epoxy glue to secure it in place.... now it does thru the cup-like plastic part)

Now it's a much much stronger joint. i don't think it will ever break again. The epoxy alone is tougher than the plastic. if the ones i repaired do break in the future i might try to make them out of metal.. would need to find a machinist to o the work ...or sell my Bravo and get one with manual AC... but that also has one of these plastic bits on the recirculate flap that is the worst one to replace... so.. maybe a Golf?
Here are some pictures:

IMPORTANT: if you are going to do this be aware that positioning of the teeth on the metal part in relation to the cup-like part in VERY IMPORTANT!!

Also the positioning of the motor in the right place is also very important. there are 5 wires that goes to the motor (2 are power and 3 are the position of the motor.) you have 2 potentiometers.. as you moves the motor clockwise one will rise in resistance and one will get lower; when going any clockwise it will be reversed.
If the motor is not installed at the correct notch on the plastic bit the flaps might be hitting the end of travel in one direction ( and force the motor..possibly burning it or braking the plastic bit again) but only go halfway in the other direction.
basically if you use the OEM part you can still go wrong and get the conector 180 degrees out of where it should be.
Thanks lyubohar thanked for this post

Re: Air only flowing to windscreen, not blowing through passenger vents or footwell.

Aurick, i think that yours mod isnt good solution.
Those plastic linkages are made to be broken. If linkeage wont broke, actuator or flap will.
Plastic is cheaper than actuator or flaps inside vent box.

Actuators can be reached without dismantling whole inside of car. It is hard, but much easier than ripping inside.
Only recirculation actuator is very hard to access, but maybe i will find the way
