4 Wheel Drive/SUVs: ac, chev tahoe, relly

Question
2003 chev tahoe.  A/c cols great both rear amd front.  but sometimes when i start vehicle, the blower speed is up high but on the control but the blower is not blowing hard.  after a while or after messig with the blower control does work like its suppose to.  like i said, ac is works very good and cool.  my guess is something electrical.  any opinion?  thanks

Answer
on some of the 03 models there is a blower delay built in to the A/C. This was used to keep the A/C from blasting you with that burst of scorching hot air on a hot day until it got cool. Leave it in auto and start the truck. Once it starts to blow air relly low just wait and it should start picking up in a few seconds. If it never starts blowing air on high, there may be a problem but try just letting it do what it wants to do and see if it doesn't pick up the blower after you can start to feel cool air coming out of the vents
