What causes this and how do I fix it.

Had it flushed about a year ago. The place that did it says they use a coolant that works with both red and green. (I don't remember what color theirs was) I thought after I had it flushed it wouldn't happen again.
So basically another flush...

Air in the system can also cause Dex to do that. I'd flush it, drive it for a while and flush again then refill w/ conventional green coolant. Might want to consider backflushing the heater core as well.
You aren't loosing any coolant are you? Being a 98 I'd think you have had the LIM gaskets done by now.
My grandfather SAID he had the LIM's replaced for me about a year ago but I'm very skeptical. Engine looked the same when I got my car back. ( It's on MY to do list.) and I think I am losing coolant, just added a gallon today. It's not hitting the ground tho, it's burning off, but I don't smell it.

Coolant flows from the radiator through the bottom hose, through the block to the top, and back to the radiator through the top hose. By backflushing, you're pulling the top hose out of the rad and dumping water in there. I recommend also loosening the bottom hose from the radiator (leave it attached to the block, though), and point it towards a bucket/drain pan of your choice. Flush away.
If it's really caked in there, run straight water with two bottles of Prestone flush/cleaner for three days (which may be dicey as it gets colder, depending on where you live), and then flush again.
If you're lucky, you'll not have to replace the rad/heater core, as Dexcool shortens their lives.
Welp! She over heated today. Pulled in the yard, temp hand was WAY high, but light never came on. Steam and coolant bellowed from under the hood. Popped hood and the steam was coming from the passenger side of the motor near the water pump. Engine was too hot to check out and it's too darn cold out side also. Just based on that info can any one give me an idea at what's wrong or what may need to be fixed?
My thoughts as of now (along with severe aggravation, because I don't have the money, time and it's too cold for me to work on it) new radiator, new heater core, flush, replace upper and lower gaskets.

how to flush the coolant.
remove the t stat, put the t stat housing back on, take the upper hose off the radiator, then push it down to the ground to a bucket or let it fly.
get your garden hose out, put it in the rad turn it on, then fire up the car, let it run till clear water pumps out the top hose.
then turn the hose off, run the car till no more water comes out the upper hose. then turn it off.
put your t stat back in, with new gasket, the upper hose back on.
now take 1 gallon of full strength green antifreeze, not the 50/50 crap. ( parts store cheap green is fine to use) dump the whole gallon in the radiator, fire up the car, fill the rad with hose water till its full. top as needed till its ready to be bled of air. it will burp and take coolant as the water in the block warms up the t stat opens up for a few seconds till cold coolant hits it and it shuts again.
now to bleed the air out, let it idle rad cap off till the fans turn on, (when the fans are on the temp is over 195 deg, the t stat is wide open) then open the bleeder screw on top the t stat housing a few turns till a steady stream of coolant comes out the hole, shut the screw, top off the rad. cap it.
done.
once it cools off check your coolant elbows, one may be leaking.
the lim gaskets, look on the side of the head where the lim meets the head, if you see a silver gasket your ok, black, you need to change it.
being your n/a the upper gasket may have failed and is leaking into the lower intake. or the intake has a crack by the egr tube.
Hopefully your headgasket's ok.
You didn't blow a head gasket. They rarely go on these cars even if overheated. What likely happened is that the upper coolant elbow ruptured and sent coolant everywhere, which just happens to be located above the waterpump.
If you take a look at the LIM where it meets the head on the passenger side and see black between the 2 then the LIM gaskets need to be done. If you see aluminum/grey color then they have the updated gaskets.
Finally had a chance to look things over... As figured I don't see anything other than coolant sitting in spots on the frame. I don't even know what to check. I let it run for about 5 min. Temp gauge never moved. No hissing or spewing.
I'm thinking of just replacing the radiator, thermostat, coolant bottle, both hoses and that plastic elbow that's goes to the tensioner. Opinions/advice please
Can someone post a link for the how to replace the ac/heater fan (blower)

that depends on if the rad is clogged up.
if you pull both hoses off the rad, put a hose in the lower port and a hand over it to seal it off some what, and let it flow up and out the top port, that will back flush it.
then fill it and let the the lower hose just dump, aka let it drain as fast as it will. it should drain rather fast if not clogged.
then theres the cooling system flush/cleaners. that should clean up the rest of inside the engine.
that brown snot can keep showing up for years tho, yours does seem to be thick on the cap. i get little boogers on mine here and there.
It will but in small amounts. Depends on how good of a flush you do. Given that it's that bad, it should really be driven for a week or two with water and flushing cleaner, as long as there's no chance of freezing. You say cold, but my definition of cold is the weather outside my house right now, 20°F. (just looked at weather for texas, low is 31 for tonight but after they're plenty safe) After a week or two of water and flushing fluid, I bet a ton of that sludge will have broken up and surfaced in the rad, which you must flush the system again and maybe use the same stuff until it stays clean.
