Hello all,

I have a 2002 Explorer Limited with the electronic dual zone air conditioning and heating system. I have ran into the problem of the passenger side blowing warm air in the driver side zone blowing very cold air.

I ran the self diagnostics on the AC control head and got the following errors:
12
56
00
02
11
21

I was advised to purchase a Motorcraft part number YH-1759 actuator motor. I have been unsuccessful with my attempts to locate a shematic of the system. I am assuming it has two actuators and not one? I know one exists on the left side above the gas pedal area which requires removal of the center console. I am unsure of where the second one is. I guess I would have to replace both of them? I called the local dealer and they said I would only require the 1759 part to fix it.

For those who have experience, would you be kind enough to advise where I can find a diagram and if I actually need two actuators?
