My truck started to overheat when it was in the 80's. Now that it is in the 100's anytime I stop at a light the temp. gauge starts going up. Today it was 1/4 0f the way from overheating. I have check the fluid and it is good. The oil was changed a few weeks age and my tires were rotated. Every time I have taken a vehicle to the dealer the problem is not coveredand then they charge me $100+. This maybe a stupid question(after all I am a female), Could it be a fuse?

A simple fuse? Not likely.
More likely is the thermostat.

Are you still covered under your base warranty?

But, perhaps more importantly, what was the $100+ charge for?
Did they diagnose something and found that it wasn't covered by your warranty?

I may have more questions to ask you about this...

Yes, it could be a fuse, especially if it goes to the thermostatically controlled cooling fan. Cooling fans failing to operate properly is a major cause of engine overheating. Check all fuses in the under-hood fuse box. Here's how:

Hi, my Colorado, is overheating usually when I'm at a stop light, wants to get to 3/4 of temperature level, I cheked:Fan clutch and radiator (had it opened and cleaned, no rust in there), mechanic said was OK, changed to new: thermostat, temp. sensor, water pump, antifreeze 4 times, radiator cap and it keeps doing it. I'm going crazy, any idea?

Not crazy, just overly cautious. Many of us are.
We worry when things look a little different than we're used to. If your temp gauge rides higher during high-temp driving, you notice. Nothing wrong with that!
But overheating symptoms could include, but are not limited to: temp gauge going into the RED, steam from under the hood, having to add coolant to either the radiator or coolant jug, "chocolate" foamy engine oil, etc. The list can grow.
One thing you may try: next time you see the temp ranging higher than normal and you're concerned, stop at your mechanc's place and have a diagnostic scan tool connected and read the actual tempurature to see exactly what the temp actually is. You are probably fine.
