There is no switch for the fan. I only know the location of the fuse, and don't know where the aluminum t-stat is according to your advice, I'd have to do some homework on that. However, I do have a thermometer gun and will take the temperature when the fan clicks on and off. Its hard for me to tell if the fan is running or not because it seems fairly quiet at least, to me...
I had to lightly touch the belt with the tip of an allen wrench to see if it was moving since it runs so fast and smoothly, it was hard to tell if it was indeed running, like I said, for me the fan runs quietly, compared to say.... my car.
Other people don't seem to have a problem telling when their fan clicks on so I guess it's just me...
I'll test out the temps in relation to the fan the minute I got free time. Right now it isn't hyper critical since it's not hot yet and I'm not taking any crazy trips at the moment, but I do want to get this issue resolved because I hate seeing the bars hit 6 out of 6 and then having the fan kick it down to 5/6 bars. I almost never see 4 bars unless on the freeway going 45mph or above, that or I'm riding around the neighborhood at night with no traffic lights, just stops signs.
