Replaced the blower motor and it had been fine until yesterday. it stopped working on high speed but the other speeds are fine. I replaced the resister and fan control switch with no change.

Check the blower motor relay. On high speed it should turn on and send full battery voltage to the blower motor when it bypasses the resistor block. Could be the ground or relay itself.
