    there is a way to lock them and take over with driver command and no it is not in defrost mode. when the system is on press and hold the auto button for a few seconds. it will take over and adjust the blower speed and blend door settings as this happens the arrows will lock and you now have driver command. then set your desired blower speed, temperature, and position this will take it out of auto. it will stay locked to drivers command until a passenger adjusts their side, even with ignition cycles. hope you enjoy.

    Wow! Thanks. I notice that the heat coming out of my vents is not all that hot unless I have both set at 90. Many times I will have the driver side at 90 and just reach over and spin the passenger side. It usually happens that I do not get the passenger side up to 90 and I have less than max hot air blowing. I am going to go out to my truck and do this right now!
