When we first start the car nothing is blowing from the vents. The airconditioning doesn't start blowing until we have driven a few miles then all of the sudden it starts blowing. Any ideas what could be going on?

 

some cars are smart
( say u want it could it will cool down first then turn it on , same thing with warm air)
this way u dont feel the warm or cold air

but the question is how long does it take the first time

what about a short drive u get out and back in does it start right away

if there is a problem it could be a module problem detecting temp, but i dont think u have a problem seems like the norm
