So, lately I have been hearing a weird noise right between the engine and the dash..towards the glove box. I hear it when the car is off, music is off and I hear nothing but the noise. It is a weird bubbling noise...not really loud but not silent. My engine is around 197-213 when I hear it. Its driving me crazy, what is the problem?

I have a 96 deville with 110 miles

Thanks for the help!

Coolant line? Heater Core? those are my first two ideas.

Sounds like air in the heater core. Check the purge line. It's likely plugged.

lol could u help me with that purge line? location and steps so I can check the problem? lol its just driving me nuts.

Am I damaging anything if it is a plugged purge line?

If it is plugged you may overheat as there will likely be air in the system.

Here are a few of many posts regarding the purge line.
