What is a kluncking sound coming from the dash after start up it thump's about 4 time's in a row and then stop's it sound's like a flap or something?

I think I have tracked down the clunking,,i believe it's got something to do with the heater, when I change the air flow from the floor to the dash is when it make's the clunking/flaping noise. Even tho nobody had a answer for me here I did find alot of question/answer's on the board that will and has helped me with my jeep. Thank's to whoever started this forum.

Robert additional info: It is indeed connected with your heater/ac. The noise is the flaps in the air control part resetting to send air in the direction that it is set to go. If you want silent air flaps you need to buy a Porsche Cayenne SUV or something like that.

Welcome to America. PS - If it stops making that noise you will have worse problems than just a lil bit of noise. ANSWER Mine does the same. Its just the heater fan.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
