Ok, so when you get a flat tire, you're supposed to put the car in FWD mode via a fuse. Wouldn't it make sense thagt switching out of AWD would result in higher MPG? I'm thinking that 80% or more of the time in my area there isn't any advantage to AWD for your average 9-5 commuter...

Has anyone tried this? Any negative consequences?

Maybe I'm missing something.

Maybe the AWD system doesn't like being in FWD mode for any length of time, but I've never heard of a solenoid burning from being enabled for any duration of time.. Kind of like your light switch wearing out because you leave the light on all the time.

I've read on other forums about people using FWD mode for various reasons (dyno/emissions testing, rear differential problems, drag racing, and of course flat tires). I'm guessing, based on current feedback, that nobody has actually tried this. I'm not, of course, saying that its a good idea.

While it would be a Bad Thing for this fuse to blow, it is also extremely unlikely as it has a very low power draw. Its not like it flows more power based on throttle position or rpm or anything.
