It sounds like you have a blower motor relay that is stuck on, try to remove it to see if the blower stops.
Here are some diagrams (below) and a guide that will help us fix the problem. The relay is #107 in the last fuse box diagram
I included the wiring diagrams for both manual and auto system is case we need to go deeper.
Please let us know what happens so it will help others.
