How to reset an interment cluster on a 2003 ford explorer?

I have a 2003 ford explorer, and just put a different interment cluster in it from an 04 explorer I found at the junk yard. The interment cluster is half way working. The radio, ac, and the windows started working again after I replaced the cluster. But some gages don't work and the gas gage is stuck on 1/2 a tank. How do I reset the cluster completely? I tried pulling #15 fuse from the fuse box under the hood but it didn't work. Any suggestions?

Ford Explorer Staring issues - Clicking sound?

So I have a 05 Ford Explorer v-8. It has been having trouble turning over lately. It would take holding the key down for a while to get it to start. This all started after some serious rain storm we had. I change the spark plugs and it seemed to be way better. The check engine light turned off but then as I go to get in the car today, I turn the key and all I hear is a clicking noise. Every now and then it trys to turn over but then clicks.

What could this be?
Does it sound like just the battery?

Would this problem be connected to my low coolant issue?

So I've been noticing for a little bit that my coolant level would become low. I would fill it and within a few weeks it would be low again. When I checked it tonight the coolant tank was almost empty and I seen a crust like near the alternator. I've taken a few pictures to show what I'm referring to.
The arrows point to where I can at least see it. There's some all the way in the back (top arrow in the picture).
Thanks

Accidentally emptied tran fluid pan?

So long story short I emptied (not totally still some dribbling out by the time I figured out my mistake) my trans fluid pan instead of my oil pan. I have a 2009 ford explorer so it doesn't have the tran fluid stick to check from. My local auto shop is 5 miles away and I don't want to do heavy damage to the transmission. Will I be able to make it down there or will I end up trying to buy all the necessary tools to fix it.

Noise and vibration coming from my 03 Ford Explorer front end?

I've been having some vibrations coming from my 03 ford explorer. It originally started off as just a humming sound coming from the front of the car, then it progressively got worse, its worse while turning to the left. And recently it is also being accompanied by a rattling noise from underneath the vehicle. The rattling is more pronounced while accelerating and can usually only be heard with the windows open or from the outside.

I was just wondering if i could get any input on what could be causing this. Any help is greatly appreciated.
