You need to replace the blower motor resistor. It is a circuit that uses different resistors for different speeds. They routinely burn out....
P1683. Speed Control Power Relay Or Speed Control 12 Volt Driver Circuit
sounds more like blower motor resistor cost about $30.00 from dealer and 2 screws hold it in place
Perhaps a bad fan resistor
Engine code P0507 mean High idle speed. Check out the the idle speed control motor(ISC). LOCATED near the throttle body.
Electrical contacts in the first 2 positions have become either corroded or burned. Replace fan speed control switch.
You may need to repair the control speed board. It's a classic fail.
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.

bad blower resistor
Not much you can do to repair that other than replacing it.
Are you serious????
Probably there is something loose. If you frequently go at that speed, I would suggest you consult with a repair shop.Probably there is something loose.
