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? |

Shoot, you did say "behind the gas tank". I should have realized you meant the fresh air fan. My advice was all intended for the heater blower, which is what I thought of when you said "defrost fan". Sorry about that.
I'm not sure what feeds the fresh air fan, except that one of the relays on top of the fuse panel sends switched power to it. And to lots of other systems as well. If you can figure out what else gets powered from that, check if those things are on or not. --DD |
