    EDIT please read new info at bottom of page..

    I have I had decided to clean the a/c condenser using foam bacterial cleaner , i accessed the condenser by removing the floor vent and opening the blower damper as per this thread Mold Smell in 2010 Prius | PriusChat

    Everything was going fine until the damper started closing so I tried to stop it with my hand , I must have broke something as the damper now feels like it is not connected to anything and just drops down shut all the time. so now I need to work out how to fix it .

    My car is a RHD the blower motor is in the left passenger side I cant see the actuator there so I am guessing that it is on the right drivers side .

    If anyone had a manual on how to get to the damper actuator mechanism that would be very helpful

    EDIT I have found the acuator and the cog that works the flaps had flipped of when I stopped the damper . it sits behind the footbrake on the RHD model , It looks undamaged but I done know which position it needs to be in to work the flaps properly.

    Things have gone from bad to being really bad , not only did the actuator cog come off the BUT the end of the damper has sheared off , so I am 100% screwed I cant even begin to work out how to replace the damper , it looks like I will need to take the whole vent system apart .

    In the US repair manual, the dash comes out. Tedious, but otherwise approachable. There will be a lot of little different screws and fasteners to remove. Work out a way you're going to keep them all organized. I would normally give the US, techinfo.toyota.com link for the manual, but you'll want to find the local equivalent for the manual that will show the right-hand drive details.

    We had to have the entire hvac unit under the dash replaced when the damper that switches hot/cold failed. &#%#*@! Cheap plastic parts and toyota says no individual replacement for cogs and dampers. Have to take the dash out just to get good access. It was a few years ago and I think install cost me about $2100 and that is with $500 off originol quote and included over a day of labor. No local shops would consider doing the work.

    SM-G920V ?

    Reminds me of a microwave I keep patching up. The cheaper model by the same manufacturer has a simple door latch, but our has this tricky push panel that runs through a series of pivots and cogs, to essential to the same thing: open the effing door. There's a plastic piece that's weak, a couple of times now I've torn it all apart and cobbled solutions, with metal rod, pipe strap, what have you. :rolleyes:

    Same thing with our dishwasher, except with that I have to buy a new switch every few years, $40 a pop, and getting harder to find.

    Thanks for all the replies , I had guessed I would need to take the dash apart to get to it . As for the part I could get the damper out of a scrap car by cutting the side of the damper box out .

    My plan now is to attempt a repair as I will only need to remove the parking brake pedal to access the end of the damper.

    As the end of the damper sheared off at 45 degree angle I am going to attempt to glue it and put a 2 or 3 mm screw through the broken piece and into the damper , I am not very hopeful it will last , but it is worth a shot.

    I tried a putting a dab of PVC pipe glue on the part last night but it did not adhere well enough , can any one recommend a good plastic glue ?

    I would appreciate if you could post the link , it will at least give me a idea , I am also trying to find out the position the dampers need to be in when I refit the big cog..

    The servos definitely show as available separately in the US parts catalog ... I'm guessing you would be looking for the RHD equivalent of 87106N. Just need to find the right part number for your market and VIN. Maybe toyodiy.com ?

    Once you have the system apart and easy to see with the servo in your hand, I imagine it won't be very hard to see how things need to fit in the cam. It needs to have the fresh air damper open one way, and the recirc damper open the other way, and as you play with the pieces you will probably find only one way that they fit and actually do that.
