I replaced the air door actuator in my 1994 Chevy Cheyenne C1500 and its a real fiddly job as the part is located under the dashboard on the passenger up near the firewall. If you are getting that clicking sound up under your dash in your Chevy truck like mine, then it's time to replace this part. I got my replacement air door actuator from LMC Truck.
