Where is the 2007 chevy tahoe blend door actuator located?

The blend door actuator on the 2007 Chevrolet Tahoe is going to be located underneath the lower dash panel of the glove box. You'll need to remove the mounting bolts holding the plastic cover of the dash on the passenger side to get to it. Once You've gotten them, You can just (gently!) pull the dash out of the clips holding it, and that'll expose the blend door actuator. As You're looking straight ahead, it's going to be on the left hand side, hanging from the plastic piece at the top left by clips. Those clips can be brittle, so be very gentle as You release them. After You've gotten those, You can remove the wiring connector, and finally, there are a couple screws also keeping it in place You'll need to take out; at this point, it should just drop into Your hand.
