How many actuators in the climate control?
How many actuators in the climate control plenum on early 90s Suburbans/C/Ks?
I get no airflow at the windshield on defrost, which I find weird because it is the DEFAULT setting if the system was inoperative. Everything else is fine, all othe settings, and blower speeds. It sounds like either there is a piece of paper wedged against the ducts on the inside or the duct door is stuck restricting airflow. I count 2 motors I can see but there has to be at least one more, that does the recirc/fresh air mode. What do you think?
