Re: pwr seat fuse blowing
Good troubleshooting technique there disconnecting the defroster and seat. I'd suspect you have a problem at the switch or a pinched wire somewhere.
What does it take to blow the fuse with those two loads disconnected - the seat adjusters I presume?
Keep up with the disconnecting of things. Look under the sill plates / carpet for wire nicks. But above all, use a test lamp in place of that fuse that keeps popping. You should be able to tell from the brightness of it if your load is shorted or not - especially when the load is disconnected.
