ok i have a 04 silverado for some reason when i turn on my a/c and i have both driver and passanger on cold the driver blows cold and the passanger blows hot air. what could be the problem?..

ok searched around and guess i found out its the blending door (sp?) is there a right up on it anywhere and also is there a temp sensor in the a/c tubes?

 

Sounds like you have a blend door or a temprature door actuator not opening up or closing all the way. These things screw up all the time.

 

yea i was lookin around in some of the threads and it seems like thats the common problem specialy since mine is an 04. anyone know round about how much these things cost?

 

All depending on the option, the actuators range from $80.00 to $250.00

 

ok replaced it damn dealer was tryin to sale me the accuator for 250 bux when the bottom one that is for the driver side is only 60 bux so if yall happen to run into them tellin you its 250 tell them you want the bottom one its the same damn part.
