2005 Silverado HVAC Mode Door


Recommended Posts

The problem I am having is that when selection modes on the hvac unit (Vent, Vent/Feet, Feet, Feet/Defrost, Defrost) the modes change fine but I don get much air when choosing the inbetween settings Vent/Feet and Feet/Defrost. I get a lot of air flow when choosing vent or feet or defrost. I have watched movement of the actuator located under the drivers side dash and it moves freely stopping at different points. Is there another actuator for the inbetween modes.

 

Thanks in advance for the help,

 

Bryan

There is so many threads on the blend door issues.. Use the "search". Many will not answer blend door issues because there is so much out there.. You do have another blend door, seems it is up in the dash more (not nearly as much fun!!!). Not very much help for you but..... If you have recently changed a battery or had other issues like that, you may want to search or blend door calibrations ect..

 

Good luck!
