Long time forum reader - but this is my first post. My car is a 2011 Prius 2. I had the dreaded "rodent in the cabin air filter" problem and thanks to this forum was able to disassemble the required cowling and after cleaning, install a wire screen to prevent future nestings. Although the little bugger made quite a mess, the only real damage was the filter itself and a little bit of the housing on top of the filter. In the process of cleaning things out, I must have done something to the mechanism that changes the flow of air from fresh to recirculating. I can actuate the buttons and make the diverter bring in fresh air but it will not move the other direction to block fresh air and draw from the cabin. If I manually move it to the recirculating position, it will close if I press the fresh air button. I don't know how the actuator moves the diverter so I'm not sure if I broke something or if it just got disconnected in the cleaning process. Anyone else have experience with this part of the cabin air system? Any help would be greatly appreciated.
