^ Tony, have you tried pulling the red 10 amp "Display" fuse in the underhood fuse panel on the pass. eng. side? Pull it, turn key to on/run a couple times and reinsert the fuse. This will often relearn the mode (vent) actuator. If no luck, may try disconnecting the neg. batt. cable for a few minutes then reconnecting. I'd try these 2 things before replacing the mode actuator. The fuse pull has worked for me and several others, but only for rebooting the mode actuator, not the other 3 actuators.
