I guess I will. I will call around and see if I can find a used flap or go to the dealership to see if they sell just that. I doubt it but I will give it a shot.That flap closes when you completely turn off the climate control or when you turn off the car. I guess it won't hurt staying open except the fact that dust will enter.
I don't know if the flaps close when you use the Air Recirculation mode though.. better change it
Mine started chirping two years ago only when it was really cold out. This past fall it would chirp when the A/C was on for a while, now it chirps all the time. Glad I found this DIY for it!Mine started making this noise today. Of course, temps in the Kansas City are were around 5º F this morning, so the cold may have contributed greatly. I'm going to keep my ear on it.
Great DIY, Paraklas. We can always learn from others' mistakes. Thanks for sharing your wisdom and for being so detailed in your write-up.
