Got home from the autox yesterday and noticed something running when I shut the car off. Thought it might be fuel pump but it wasn't. Instead it was the defrost fan behind the fuel tank.
I tried pulling all the fuses and it never shut off. Any suggestions on where or what to look for? |

You mention the lever being up
Are you refering to the one on the floor? If so doesn't that just control the blower motor back in the engine compartment? |

Yes, the lever on the floor. Pulling it up opens the flapper boxes to allow heat from the exchangers to pass through the longs and into the passenger compartment. As Dave said pull that lever up high enough and it grounds the blower motor circuit so the blower motor gets power and runs (assuming the relay is working correctly). |
