Is there a relay and If só where is it located?
My car has 222000 miles.
My car has an automatic transmission.
The blower motor controller is mounted in the right side of the dash near the blower motor. These modules are the most common cause when blower motors keep running. If you replace it, and the motor keeps running, then you have problems with the A/C control panel which will need to be diagnosed for any trouble codes.
I’d recommend getting some help from a qualified technician who will be able to diagnose the issue with your A/C and fix it accordingly.
