It's been getting incredibly hot where I am, and using the AC full blast, and having to run errands, I've noticed that any time I make a stop when I turn off the car and leave it in the ACC position, it will leave the fan on for maybe 30 seconds or so (I have a mishimoto thermostat and fan switch) - this is totally normal, because I know the fan switch kicks on at a lower temperature than the OEM unit.

But I was wondering if there's anyway to play w/ the relays on the car so that the fan would come on whenever it was needed regardless of keys being in the car (or in ACC position), similar to a turbo timer of sorts. It's not something that's needed, just wanting to know if anyone has ever done anything like this, or know how it could be done.

thanks in advance

 

I once saw in a shop here, a fan timer, which is similar to the turbo timer, its also an on or off switch for the fans, for example when you have a drag race they use it to switch it off so the car wont use any extra electricity. saw it a while back though.
