I started my car an a weird banging nosie started for about 20second. It was comming form behind for glove box. This has happen three time alway. This only happen after i started the car, but it does do it all the time. Anyone else every had this problem too??

 

Bump!!

 

Perhaps it is the recirculation vent for your air con? Try turning your recirculation on and off. Or turning the A/C on and off. BTW, if you turn off your A/C, I heard that you should not turn it back on for a couple of minutes because the system is still pressurized.

Just a wild guess...
