The blower motor just comes on by itself, with the key out of the ignition switch. it runs a while and cuts off and if you turn the ignition on for a few seconds it will turn off. Ignition switch is fine no extra play in key and it locks in place fine when turned off.

Hello,

The blower motor speed resistor is out that's what they do when the go bad, here is a diagram of its location (below) so you can get the problem fixed.

Please let us know what happens.
