this happens when I put the temp at 65-70 and I hear a banging noise coming from this part that is pictured. When I push on this the noise goes away,this will happen with the key on and fan on. I really do not want to pull the dash out but any help would be greatly appreciated.
this is a 92 xjs convertible.

From this are we to infer that the noise *doesn't* happen if the temp knob is turned to a higher setting and/or the engine is actually running?

Is it a single bang or repeated banging?

Well, we have to start the discussion somehwere, so.....

My intial gut feeling is that the flaps which control air flow are fighting each other due to phyical interference between them. Does that sound plausible? Just a guess on my part.

it does not happen when the temp switch is turned up-it does bang and very very loud when the car either running or not-it continues to bang until the car is turned off or the temp is on hot.

 

Hmmmm.

I'll continue mulling.

Meanwhile let's hope that others chime in
