03 Chevy blower motor wont shut off

[Cpelley1]

When I shut my truck off and remove the keys, I can still hear and feel air coming out of the vents. My truck has the dual climate controls and for the last few weeks the blower only works on low but then every once in a while it will work on high. Now I have to pull the blower fuse every night or my batteries are dead when I go to leave for work in the morning. Any suggestions????????????

check the resistor underneath the blower motor where the wires all plug in you have to take the skirt off the bottom to see it

^^^^ That's it, except it is called a "module"- make sure that you get the right part (there are different plug ins, yours SHOULD have the 3 terminal plug in the actual module itself). Shop around, dealership is EXPENSIVE- my local O'reilly's couldn't get it (they could get "resistors" for that year, but the dual climate control makes it a "module" apparently, and there is a difference), but I found a place where I can get delco parts (not a dealership) and it was around $50...- dealership quoted $140)
