2005 3.0 Aux Fan and Fuse Q's

[ylwjacket]

OK, I may be the dumbest self-wrencher out there.

I just replaced my water pump, thermostat, and upper and lower hoses. Everything was fine, for a few days.

Yesterday, in traffic, the car overheated at idle, and a/c got hot. Let it cool down, started moving again, and it was OK as long as I was moving. It happens quickly if I'm idling on an uphill, and slower if I'm pointing downhill. In fact, I'm not sure it happens downhill at all.


It was actually doing this prior to the swap outs as well, but I thought it might have been related to the faulty thermostat (dealer had told me thermostat was stuck open).
Now, I am feeling like it's the aux fan.

I have searched all over and can't find answers to a few basic questions (herein comes the dumbest part):
- which fuse controls this? I saw 61 on other posts, but I wasn't clear if that was a 3.0 or a 4.4. Auxiliary fan, or anything like that, is not labeled on the box.
- i saw some info about testing the fan itself, but I don't see any electrical connections to the fan. Do I have to take the bumper off to get to it? Where is exactly is it?

I saw info about fues 61, but like I said, I wasn't clear what model that was for, or if it matters. Also, I saw info about testing the fan itself, but not info on where the connector to test is located.

Of course, I really don't feel like replacing the aux fan unless it's necessary.

Also - does the uphill thing indicative of anything other than I live in a hilly place?

Thanks,
Mike

Not trying to be too antsy, but I wanted to bump this to try to get some help with this answer, so I can get this resolved over the weekend.

Thanks in advance for your help.

The power for the aux fan is located on the top left of the fan itself if you are standing in front of the car. There are two connectors a smaller one and a bigger one, the bigger one powers the fan I believe. If you turn the car on and the AC and unplug plug it back in you should see the fan spin a little bit if the power relay to the fan is working at least this is what I have gathered so far in trying to get mine to work.
