Auto Climate Control woes...
Whenever I switch on the AC..heater or the fan I hear some flap close or open after sometime with a thud...The thud is very loud and can be heard very distinctively...Is this normal...??
Would appreciate any feedback...

Yes, they are vacuum operated. Flaps can actually be checked with a SDS or HHT. However, if you have a hand held vacuum pump you can check one by one at the distribution block. Block is located under dash (passenger side).

Star Diagnostic System or Hand held tester.
If you want to check it yourself you are going to need a hand held vacuum pump. To reach the distribution block you need to take off plastic panel under dashboard, on passenger side. You should see it attached to the blower box. Bottom portion pops out and then you can slide it down.
