    Hello , I change in december the blower motor because dosen't work anymore maybe if I hit manny times will start but dosen't blow too much air , after I changed the front defrost and the leg vents dosen't blow air , not cold not hot, nothing I have the error 43 on display if I am in diagnostic mod on MFD , should I change the servo sub assy damper ( for mode ) or I waste my time ?
    I am afraid to open the dash and everyhing , thank you .

    Yes it sounds like you're messing with the servo or dampers or the damper motor that positions the vents to where you want the air to escape and blow on you or not working there are many reasons Yes it's a pain in the butt to take it apart many people don't opt to do so. Sometimes on these cars when I have this problem I can get them into a position where I can leave them pretty much year-round so I don't ever really fool with him I'm not under any speed requirement so I don't have to jump in the car and roll out the driveway at a certain time in the morning everyday than inclement weather like Frost and fog.

    I triet to swich manualy from legs to front and I can hear something I don t know if they work or not but I noticed some sounds when I change , I think this problem is very old because I remember even if I put for example to blow on windshield and legs still blow on face but I don t care at time , now it s a problem with windshield and I am thinking how to fix it .

    There's a whole bunch of discussion on this site about the vents You can look in a search on this site there is pages and pages and pages and pages of discussion about this You could read for a whole night I promise I have looked I haven't done all the reading You will age a year looking through all of it basically it comes down to the servo motor devices that are bolted to the air box that swing pieces of plastic back and forth to make positions equal to the pictures on the multifunction display I am sure if one wanted to you could unplug the devices the motors push the plastic pieces to where you want them to stay and that would be that but humans aren't that simple they're going to want to be pushing a button all the time and playing with things that's how they got broken in the first place so there's always that It's a kind of a pain to mess with but you'll get it there are pictures lots of discussion and more pictures that is really here I'm no one is going to come and retype all of this again I'm pretty sure I don't know if in other countries Prius shows up and different respective languages or not but I kind of doubt it.
