Thank you for your service to our country. The electrical section of the ignition switch is an inexpensive part. The replacement seems to cure a myriad of mysterious electrical problems. If the problem continues that would be a good path to follow. There is an incredible amount of good information on this site. I have researched every issue with the search function, that along with the 101 projects book and forum responses have made me fearless in maintaining, repairing and upgrading my Boxster. Here is a link to the parts for sale to illustrate that clusters are readily available if that truly is the case.

Please post the resolution of this problem, and once again THANK YOU.
