A/C mode selector does not work. Blend door actuates (Temperature changes from cold to hot). When changing the mode, the load on the fan seems to change but the air flow is still in the vents and will not change to defrost or floor. How many actuators are on this vehicle and which one controls the flow from floor to vent to defrost. There is a panel that blocks the one actuator that I can see. I need detailed instructions (hopefully with pictures) on how to remove any panels that block the actuator and the removal/install process. I will generously donate if a workable solution is proveded. I pay for results.

Nice to hear :0) there are 2 mode actuators, yes the one of the mode actuators is bad and needs to be replaced here is the location so you can make the repair. Once the repair is done reset the HVAC system, this guide can show you how. I would remove one of them and work the pivot by hand to see which one does what.
