Default Blower motor

The blower motor runs on high and can't be shut off without unplugging it on the motor. Key off and pulled out and the fan runs. unplug either plug on air housing also shuts fan off. Must be a relay somewhere but were. I took the control out of the dash and the fan still runs until I unplug it. I took the control apart and cleaned it now all the buttons work but can't shut the damn fan off. It's a 96 LT4 with electronic temp control. It's driving me nuts so any help is greatly appreciated.

Look on youtube to see how to run the self diagnostic on it. Not sure but believe the relay is on the housing on the pass side I am sure someone will know for sure.

Blower control module is probably shorted. Mounts on heater case has 2 connectors.
