My wife's Grand Prix is acting like normal. My Radiator blew on my 08 Subaru. After she gets attention the Grand Prix wants some. Not kidding 3rd time this has happened after a repair to my car!
Only when about flooring the 08 Grand Prix base model do I get a hissing sound from under the dash. Sounds almost like a boost leak. The engine is N/A.

The 4th post down on how to check this is broken. I have not been able to find it is any other posts. Trying to find a good DIY to check out this issue. Not looking forward to removing the dash if I have to.
Heat does seem to be working well. Last year flushed out the heater core. Worked great all last winter.
Thanks for any help
