relay noises after start.

relay noises after start.
09 hhr ss automatic.
When I start the car I hear what sounds like a relay thumping.
I happens a few seconds after the car has started.
It thumps about a dozen times an then stops.
I sounds like it is coming from behind the glove box.
Everything seems to be working.
Any ideas?
Thanks

My guess would be a hvac actuator in its beginning to fail.
That have plastic gears in them and jump gear teeth when there worn.
You can try and change the control settings temp. & mode to see if the noise is there when the actuators move.
