Blower won't shut off

Greetings all, I have a 2009 Nissan Titan and i cant turn the blower/fan off, heat and A/C work but I cant turn of the air....any help is greatly appreciated.

Thanks to all

Likely a bad blower motor resistor. They cause all sorts of issues when they go bad.

thank you, my own research also states that. somewhat easy fix.

Steal the, it was the motor blower resister, I got one from the local parts store for $52……didn’t work, so I order a Dura-last for $75 and it solved the problem….you get what you pay for.
