Blend Door Actuator Location
1995 gmc g2500 vandura blend door actuator location? I think mine needs replaced! I only get heat out of my defroster and can't switch vents.

Re: Blend Door Actuator Location
Hello.
"Stuck on defrost" is a pretty common problem. The blend door is actuated by engine vacuum. 99% of the time the vacuum line from the engine is rotten. They deteriorate quickly from the heat underneath the hood. Replace the vacuum lines and check-valves, and check the vacuum tank for leaks.
