The fan motor has failed and will need replaced.
If the HVAC blower motor does not work on any speeds, I would suspect the motor or the switch is bad.
motor used in fan is universal motor, which can work both on Ac or Dc . The working principle is similar to the ordinary motor

Check the fuses, check the relay and then check the fan motor.
bad fan or bad fan relay
the fan is work by the elactercity and current and it has motor so i have to switched on and off
Check fuse first. if ok then check you have power to the fan. If not it is probably the thermo switch which switches on when the engine gets hot powering the fan motor. Be careful when checking the connections that the fan doesnt start and injure you
