there is a small circular perforated (disc) right by the drivers left ear on the in between window column that kinda chirps
for quite a while entering and leaving the vehicle
eventually stops but it is about head high
I have searched and searched, guess i dont know what i am searching for
any ideas?

opened the window column... the part is below, it had allot of lint in it , i blew it out and no more noise, YAY!

That is the interior temperature sensor for the Auto HVAC system. Periodic cleaning is beneficial.
