Blower Motor not working

Blower motor suddenly stopped working on all 4 switch positions. Thanks to thread by "Les" Oct 2012 eventually found bad connection at 4 Wire electrical connector on motor resistor behind glove compartment. This has to be pressed really tightly until "click" is heard to engage pins. Most threads recommend fitting new Motor resistor but check this out thoroughly first.
2nd time it happened I just bent the pins very slightly to improve contact and this worked. On 3rd occasion it turned out to be bad wiring connection at fan motor under top of dashboard. See posting by John.D on November 2018 under "Heater Fan Fault on K12
