99 C1500 Chevy Suburban AC Actuators - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have replaced the mode door actuator by the gas pedal and the blend door actuator on the back side of the blower motor on the passenger side.
Still no heat up front.

Is there another actuator somewhere?

Maybe control unit is bad?

HELP

I found this youtube that might help.
I didn't watch the whole thing but mention of 3
actuators was mentioned.
