Most likely heater / blower relay under hood, left side relay box marked HTR on lid, try tapping it, if not - remove relay, if motor stops running, you should have another relay in the box to substitute - as a test, if it works, replace relay. Other times a power board / variable speed resistor board can go bad and cause this issue - it will look like tin can when removed, but yours should have and "old school" blower motor resistor - it will look like stretched out springs, located under dash near gas pedal / trans tunnel in heater box. Two screws and a plug - not a big deal. the variable speed power board can keep the motor running, the old school style will not.
