Water sounds behind the dash .
The few times I run the heater ,I now get a water bubbling sound . My pedal return spring broke as well .
Both seem to have no effect on the function the car . Someone else posted about the spring ,but the bubbling water seems odd .
Normal ?

You may have air in the system and it needs bleeding out and filled to top.

My 11 gs does this too. When it's cold, it sounds like rushing water behind the dash. I posted the question here as you did and got both the answers you did. There may be air in the system and its normal. I was told it was the heater core also. And when I asked my corvette tech at my local dealer, he had no idea what I was talking about. So who know. But my car does it to and I have also had no issues with my car either so who knows.
