i think it is on the air distribution box and alot of times you have to take it out to take the actuator off which requires removal of the dash

Had the same thing happen to my truck, the blen door actuator is under the console on passenger side, but the heater core is going to be clogged if you dont have any heat coming through, but a/c works..

Hello: I have bad news for you, if you run the actuator without it connected to the door the actuator is ruined, it will have to be replaced. After replacement the system has to have the doors (actuators re-calibrated.) re-calibrated. This is done with a Tech 2, A GM special tool.

I'm having the same problem with my 00 GMC Sierra. If you do NOT have dual zone climate control, it's just to the passenger side of the transmission hump under the hush panel underneath the dash. 3 screws take off the hush panel, two take off the actuator. One screw on the hush panel is a pain in the **** to get out. I'm still trying to figure out if the "upper" or "lower" is the proper fit for it. If you have dual zone, then one is under the passenger side, and the other is under the driver side. Hope this helps!
