Well Today was a new problem, I get in the truck and the blower motor would not turn on. I could feel the. Cold A/C coming thru the vent when the truck was moving . I pulled blower motor and resister out went to Auto Parts store and purchased both. Well soon as I put the aftermarket blower in and hooked up the resister it kicked on . The blower motor sounded weird so I swapped it out and with original blower motor and it was fine was blowing strong. Well weird thing is the blower will not shut off at all now. Even when key is out it continues to run ?

I have to unplug the resistor to get blower motor to shut off. My guess is resistor is the wrong or just shitty.
