    No relay.
    Power comes from fuse#30 to the heater control module to the blower control processor to the blower motor.

    If it isn't shutting off, then you need to have it hooked up to a scantool to check it out.
    My first thought would be that the HVAC control module has a problem.

    I'm sensing from all of your questions, that you may not have a lot of experience in working on autos, and a little hesitant about jumping in and taking the hvac apart. I'm not sure you will be able to find someone, who can walk you through step by step how to do this repair specific for your year/vehicle/model. What you may want to seriously consider, is purchasing a set of factory service manuals for your vehicle, which you could get from [ Link Not Allowed ] They are very detailed, giving step by step instructions on repairing everything on the car, with pictures galore.

    The way some of the repairs are now adays, you can spend hours trying to figure out how to do something, where the instructions can take away all of that uncertainty.

    you may want to check advance auto parts online and see if your car has a a/c blower resistor. and if the resistor is bad that is your problem.
