AC keeps blowing after car is shut off.

I couldn't find an answer, everything from a relay to the entire system needs to be fixed. I was hoping that someone would be familiar enough to know if it's an easy fix like replacing a relay/single part or hard fix like needing special tools and equiptment. Thanks though for your answer.

blower power module!!!

I appreciate the response. This will show how bad I am with cars but after taking down the passenger side "firewall" is there a wire or group I can unplug that will temporarily fix the issue until I can get the part or someone to show me how to take apart and put it in etc. I have read a lot about this and get different answers. Any extra help for a person that is terrible with cars would be appreciated or should I just go to autozone or a car shop and take one for the team.

just pull the blower motor fuse out.i sent you a diagram.under the hood on top of the HVAC case,the module is on top,there is a 4 wire connector on top of the module,unplug it,or just pull the fuse for the blower motor.
