Electrical Woes

[rubbernecker]

I'm having electrical issues with my 2000 Boxster S.

My windows drop when the doors are opened, but they do not respond to the window controls. They do not come down when the Convertible top handle is pulled.

The doors do not lock or unlock with the console button or the remote. I can only lock the driver door.

The defrost button does not respond.

I replaced the C3 and D1 fuses even though they looked and tested good.

I'm getting 13 volts (when the car is on) at the C3 and D1 positions.
I pulled the console and tested voltage to the switches and couldn't find any voltage between any two of the many wires going to each switch.

I replaced the module under the driver seat with a new one from Suncoast Porsche and had my local dealer reprogram the new one from the old one's data. The only difference is that my convertible top started working soon after that.

I read in other postings about SPDT relays that are just above the fuses, but I can't find any information about which relay would be affecting these components.

Any ideas on next steps?
