Funny noise coming from heater

[tlc356sc]

I have a funny noise too when the A/C is off( fan to zero). it sounds like a slow speed fan hitting something, so it makes a very faint repeating clicking sound.
Is this the noise? If yes, is it the cabin temp sensor and what's the fix?

That's pieces of foam getting stuck in the flaps that change the direction of the air flow. Do you have small pieces of foam being blown out the vents?

Search the forum or my posts, I had the same issue. I never got it addressed, it comes and goes. I put it to full blast and it goes away. Until the next time

I know its an old thread, but its a new problem to me. At speed the whistling covers all other noises. When I slow down, with the system OFF, I hear a low pitched motor sound. I guess there is a cabin air blower behind or under the filter in the freunk. Is this a regular problem or something unusual? Car is 98 with 23K miles.

thanks
