air on my ac system blows out only through the defrost vent. 2003 silverado has a
a top and bottom door blend actuator. I believe the top on is bad.
I know what you are talking about, but the air that is coming out of the defrost is hot on
the passenger side but not on the drivers side. will changing the mode actuator solve
this problem as well.
When I move the temperature controls i do not get a change from either one. Air is
always blowing out the defrost and the drivers side stays cold no matter where the
temp setting is and the passenger side stays hot. I also have checked all the fuses
on ac system and all ok. This happened when I changed the battery out on my
I have already tried that and it made no change. I also disconnected the mode
actuator and it made no change as well.
