now call me an idiot,but regarding the following info pinched ffrom wjjeep.com regarding calibratiion after fixing the blend doors:-
Calibrating AZC door actuators
Calibrate the door actuators after making any repairs to the AZC system. To calibrate the door actuators proceed as follows:
1. Turn the ignition on.
2. Set the AZC to automatic.
3. Turn the ignition off.
4. Remove the IOD fuse from the Power Distribution Center. Wait several seconds, and then install the IOD fuse.
5. Turn the ignition on. Do not touch any of the AZC controls for at least one minute to allow the calibration function to run to completion.
now please excuse my ignorance but where is the IOD fuse in the Power Distribution Center please?
