I'm getting a... ready for this one... bubbling/knocking/fast tapping noise coming from behind my glove box everytime I get in now and start it up. It takes a few seconds at times sometimes a min. two but its loud and has gotten louder. I think it has something to do with the evap. Also it goes away when I turn on the ac blower or heater but as soon as I turn it off its going at it again. It only last for 20 seconds at most. Anyone on here have any Ideas for me? Also my car is now in storage so its going to have to be fixed this summer but how can I recreate the noise for the dealer everytime Im there it never happens. LAST but no least I know that I have condensation in my left headlight how can I duplicate this to get it warrantied out. I tired washing it and then switching temps but nothing happened I have seen The fog in the lamp before though.

 

Your entire heater core and part of the AC condenser unit is behind the glove box and behind the radio. I would bet you have air in your coolant system that is being pumped through the heater core plumbing causing the bubbling sound. The coolant system is supposed to be kept air free. Try flushing the entire coolant system and getting the air out of it...

 

Sounds like you may need to bleed or burp you coolant system.
I am not sure of the procedure for this on the crossfire but I'm sure it is similar to other cars.

 

I was reading something about a HVAC or some other electronic valve is that possible they were relating it to a mouse running around I'm thinking maybe that.
