I pulled the relay and resoldered all the joints....the seats work now....will see how long it lasts.

I also pulled all the fuses from the fuse box in the trunk and sprayed the box with contact cleaner, and cleaned the fuse terminals with scotch bright. But them back...and the window and mirror work also.....again, let's see how long it lasts.

Thanks for the replies.
