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.
