Toc Toc sound in vents

[Snowman]

Hello all,

Maybe the sound I have is normal, I tried to search but did not find mutch with toc toc.

I noticed a sound in the vents. It is hard to discribe the sound, it is a bit like if a gear would be at the end it can go and is being forced and skipes Toc...


Normal???

Thanks

I have the same exact thing. I know exactly what your talking about..but I too have no idea. any help from anyone would help great. My ac runs fine and the car is in good shape 03' with 43K. I will even hear the noises after I have just turned my car off.

Most likely bad temp flap motors. I had the same thing, and when I took it in they replaced the temp flap and recirculation motors. Problem solved.

I had the same thing, then I asked the dealer. They said it is just the vents adjusting to make sure nothing is wrong within them. It is normal. It is only supposed to happen when the car starts.
