Welcome this can be cause by a bad dash controller or the blend and temp door actuators, try disconnecting the hvac fuse for 15 secs, under the rear seat, see what happens. BTW is this a manual or auto hvac.

Re: 2002 envoy blowing cold on passenger side

Thanks for getting back to me so quick maxwedge. Its an auto. I tried Unpluggging the hvac fuse, and got nothing. Do you know a ball park price of how much it would cost for the dash controller or the blend and temp door actuators? And what one should I try first?

To avoid guess work a qualified shop would use a scanner that can access the bcm and command the various functions, this will help pin down the culprit.
