Report: Electrical Portion of Ignition Switch May Become Erratic or Fail
Porsche Boxster Problem
Average Mileage: 44,000 mi (25,000 mi - 65,000 mi)
If the vehicle cannot return to run position after start or if the interior fan is not getting power, it may be the electrical portion of the ignition switch has become erratic or has failed. The entire switch assembly should be replaced.

I changed out the switch to resolve the issue

I had the same problem. Although I could turn off the engine and remove the key, turning the key as difficult and neither the fan or windshield wipers would operate. Replacing the switch resolved all the problems. Access to the two mounting screws is tricky. I suggest using a screw driver used for eyeglasses, flat blade, 2 1/2 inches long. Replacement of the plastic ductwork requires patience as the mating end by the door drops. Pay attention as this end is not rectangular and will only fit one way.
