    Can someone please tell me which actuator controls driverside vents, I think there are three. My ac blows cold for a while then driverside vents start to blow heat if i turn off truck and resatrt it is ok .Does this sound like an actuator problem? Hope I did this right first time posting.
    Thanks for the help
