I have new blower motor. it dosen't stop running

Does it only do this on high blower setting? If so the blower motor relay may be stuck closed.

Blower Fan Won't Stop: What to Check if your Furnace Fan Runs Continuously - (the fan won't shut off on its ownFirst, confirm that the room thermostat is not calling for heating or cooling. In the heating season, just set the thermostat(s) to the lowest setting and confirm that room temperature is above that point. In the cooling season do the opposite - set the thermostat to its highest setting and confirm that room temperature is below that point. You have told the thermostat to turn off the HVAC equipment. If the equipment was running give it three to four minutes to shut down.
Next: If the blower just keeps running no matter what, there are two places to check switch settings before calling your heating or air conditioning service company in response to a furnace fan or air conditioning fan that just keeps running without stopping: At the room thermostat: the FAN-AUTO-OFF or FAN ON/OFF switch on the room thermostat should be checked. The fan control should be set to AUTO. You can try turning the switch to OFF too.

Details of checking the thermostat's FAN-AUTO-OFF or FAN-ON switch position when the furnace (or air conditioning) fan won't stop running are

Other snafus such as a shorted thermostat wire can also cause the A/C or warm air furnace fan to run continuously... At the furnace or air conditioner air handler or blower unit: the FAN LIMIT SWITCH may include a switch that manually keeps the fan running. We discuss this switch here.
Take a look at the fan limit control switch. Before pulling the cover off of the switch, just see if the switch includes a control such as the white push-pull switch like the white device shown at the lower left in our photo.
Depending on the position of this switch (pushed-in or pulled out) the fan may be on manual override - causing the fan motor to run continuously.
Check the printing on the switch face to see if you should push the switch in or pull it out to leave the blower on "Auto". ("Man" or "Manual" would be forcing the fan to run.)
