Heat/ A/C blower motor will not shut off even when ignition is turned off !

There are only 4 relays in that fuse/relay center. My mechanic and I pulled all 4 of them, 1 at a time and none of them killed power to the blower! Thanks !

You didn't find any relays on the passenger side firewall? .. Possibly under a flexible plastic cover? .. I may be mistaken, just going by memory here and that is questionable these days! .. According to the better half anyway..... It just seems like a circuit feed relay is not turning off... Good luck and Merry Christmas!
